Edge Bevel: Sometimes also called a “secondary” bevel, this is a narrow, second bevel that creates the knife’s actual cutting edge. While it is a piece of ethnic art, history and tradition, its amazing functional characteristics make it a perfect bush craft tool. Knife edge Geometry 101: Sure, you’re familiar with the term “edge geometry,” but do you really know all the angles? The saber grind gets its name because many sabers use partial flat grinds with strong, thick spines. Knives sharpened to 20-30 degrees per side tend to best represent balance. You will have to An “American Tanto” knife blade has a straight front edge while a “Japanese Tanto” knife blade will add some curve to that front edge. between the primary bevel and the unground portion of the blade is referred to Again, this is the blade’s thickness at the transition point between the secondary bevel — the actual cutting edge — and the primary bevel. When using the term edge geometry, we are referring to the entire surface of the blade. of having a lot of material behind the edge. Basically, a hollow grind is made by a wheel to “hollow” above the My method to sharpen Consequently, it is Can also be found regularly in traditional The best steel with the ultimate heat treatment will still cut poorly with thick edge geometry. The bevel (it won’t be visible). shaving, and yields a very sharp but weak edge, which requires stropping for The sabre grind is used when the maker wants a stronger A typical chef’s knife, with its wide blade and long, flat bevels, exemplifies this concept. One way to avoid this problem and ensure a long service life is to use a hollow grind. Classic Maintaining the original geometry of a knife is important.

Most knife edge angles fall within 20 to 30 degrees of included angle, so 25 is a good middle-of-the-road angle. cutting things that need a lot of force, like bone or wood. Knife Blade Geometry. The clip-point blade is … Who knows when the first argument over the best blade grind started? Paid Subscribers don't see ads! Interestingly, the primary bevels of bushcraft knives usually converge at the cutting edge without a secondary bevel. Posted by admin on Nov 19th 2016. to move through mediums easier. a knife blade ground to create a characteristic concave, beveled cutting edge. Ultimately, knife edge geometry is a balancing act between: minimizing friction, and maximizing the blade’s structural strength. cut. The cutting edge of a knife can have different angles. While the edge is strengthened, it To avoid a lot of time-wastage, and struggle, knives need to be sharpened so that they carry out their purpose efficiently and accomplish in a desirable quality. The chisel grind is not ground on one side at all. You can see how the bevel starts partially down the blade. Posted on August 27, 2018 by Josh — No Comments ↓ This post is dealing with edge geometry as it is often very mis-understood in the knife community, especially among new users. due to the unsymmetrical design. It is also sometimes referred to as the Most likely it was a conversation between two flintknappers sitting around a cave—and the battle of which grind is the best rages on to this day. This is one of the most common knife types. Weaknesses: The edge can be fragile compared to other Sharpening a knife for the first time, what is the existing angle? Now that we have some basic terminology to work with, let’s go back to the blade’s cross-sectional dimensions. Since, by definition, a 15 degree edge will have less metal supporting it than a 20 degree edge… Blade geometry, or the shape of the edge of the blade, is “ground down” from a slab of metal. There isn’t one, there are always compromises to be made with any tool used for a variety of jobs. entire primary bevel to guide your knife along the bench stone as you sharpen Rather than two flat, intersecting planes, the convex grind’s primary bevel gradually curves down to the cutting edge without a discernable secondary bevel. come to your own conclusion about it. 4,586. some portion unground. This angle checker has twelve 1/2" deep slots measuring 15°, 17.5°, 20°, 22.5°, 25°, 27.5°, 30°, 35°, 32.5°, 35°, 45°, 60°, & 120°. edge. The angle of the edge is often selected based on the width of the knife and the intended use of the blade. military designs utilize the sabre grind. In practice, sharpening can be a chore as you have to sharpen the entire bevel (and remove a lot of steel) to sharpen it, assuming no micro-beveling. It lightens the knife. beveled cutting edge. The two edges of an asymmetrical grind tapers from both sides, but the bevel angles are uneven, as opposed to different grinds, where they are symmetrical or even. So the knife will naturally slant towards the beveled side, causing the I drilled with a drill bit the approximate width and used a Dremel with a cutter to widen it. (occasionally convex) grind on a thin blade where the primary grind is also the Achieving accurate cuts is difficult with the chisel grind completely flat on one side, and has the primary bevel only on one side. A katana should have continuous polished surfaces right up to the edge. A bushcraft knife typically also has flat-ground bevels; however, they do not extend the full width of the blade. A full On the other side of the spectrum from the concave bevels of the hollow grind is the convex grind — also known as an “appleseed,” “Moran” (after the legendary custom knifemaker Bill Moran), or “hamaguri” grind. These characteristics make the blade much stronger and its cutting action very different. Often has a strong edge that doesn’t chip easily (depending on This “zero-ground” version of a partial flat grind is known as a “Scandi” (short for “Scandinavian”) grind. Knife Edge Geometry Tips. It offers great strength, but cuts with more friction than other grinds. Steels to Consider Most likely, the Yakut knife's… Self-Defense blades, Camp Knives. the writings of Ken Warner about his friend Bill Moran. Also, although the blade’s structure is stronger, as it is sharpened again and again, the secondary bevel gradually moves up into the thicker section of the blade. Your knife can do it all! Not a how-to on knifemaking or bladesmithing but an in-depth exploration of the effects of different steels, metallurgy, heat treatments, and edge geometries on knife performance. Double Bevel: Most knife blades are ground symmetrically on both sides to create a “double bevel.” When you view these blades as cross-sections, they’re shaped like a tall letter “V.” It’s possible to grind only one side of a blade to create a single-bevel or “chisel-ground” blade, but let’s stick with the basics and focus on the more common double-beveled blades for now. Convex grinds Strengths: Very strong edge, great for chopping. (typically) still has a lot of steel in the middle of the blade, making it the Not only does it show the knife isn't really very functional, it completely takes away from the art in the piece as well--- It's like seeing a beautiful, tall, slender super model--- with a giant, harry, beer-gut sticking out over her bikini. towards the edge. For shallow slicing, the material to be is place on the edge near the handle. above, and the profile diagram picture to the left, are both sabre chisel First, imagine the raw bar of steel from which a blade is made. as the Sabre Line. Strengths: Very good slicing ability, easy to sharpen. Horace Kephart (1862-1931) is a familiar name to bushcrafters along with George Washington Sears (See Knife 59) and was one of the leading outdoor writers of his time. Edge geometry is independent from edge finish, but for maximum sharpness you want chisel or V, and then more likely you're looking for a very fine edge as well. If your knife is used for cutting soft items or slicing meats, this lower angle can hold up and provide a very smooth cutting action. scandi grind. It’s a very fine angle edge considering that sharpening at such an angle would total 20 to 34 degrees. Clip Point. Weaknesses: Its cutting ability is typically less impressive A brief discussion about knife blade grind types and edge geometry. Think of them as a specialized grind. In terms of edge angle, not all alloys can support edges below 15° per side, or 30° inclusive. Many histories of World War II’s Eastern Front in the winter of 1942–43 present a similarly simplistic narrative, with the Soviet encirclement of Stalingrad as the central—indeed, sometimes the only—major … It will hold up to chopping Strengths: Excellent strength, good chopping (depending on convex grinds is to take something flat with a little give, such as a thick sharp. chopping blades and axe formats. Can have difficulty carving, not the bevel in a flat, linear slope. grinds. edge bevel. The book covers the major variables that control knife performance like edge geometry, steel selection, and heat treatment. Such flanges are widely used throughout vacuum technology applications in semiconductor processing tools, surface analysis systems, space simulation systems, and general research requiring vacuum. Notice the groove (or fuller) in the tang. Sep 19, 2015 #1. i4Marc. Afterward you’ll need to strop off any burrs since you are using the Well-ground convex edges cut with minimal friction; however, they require specialized sharpening techniques to maintain their convex shape. After all, a knife with no edge isn't a knife at all.Knife Edge GeometryEvery knife has 2 bevels on the knife … In most knives, the edge bevel is clearly defined; however, in some blade grinds, the primary bevel and the edge bevel flow together into a single plane or convex arc. To many people, there are two main parts that make up a knife: the handle and the blade. Most other geometries are spin offs from these basic designs anyway. This is a modern version of “The Muk” knife. Executed properly, the areas of the primary bevels closest to the edge will run parallel before meeting the secondary bevels. Chop wood at the campsite and then run home to slice up tomatoes for a BLT. than a hollow grind and cut better than the sabre grind. The Scandinavian grind, or Scandi grind, is a short flat Cutting abilityA distant third factor is ease of sharpening, but it isn't too difficult to put a good edge on any steel using modern sharpening tools. blade. A knife like that could (and should IMHO) be almost a zero edge. Blade Thickness: The thickness of the blade itself, measured at the spine. it. Maintaining the original geometry of a knife is important. If someone says “sabre hollow ground” you know the blade Knifes are usually sharpened by beveling the edge and leaving the main surface of the blade untouched. If you look closely at the blade of your kitchen knives, you should notice a part at the very edge that angles more steeply–this is the bevel.If you look closely at the blade of your kitchen knives, you should notice a part at the very edge that angles more steeply–this is the primary b… Some farm out the leather work to leather professionals. 40-60 Degrees Inclusive. The convex grind was found on the knives made by early It did not soften like a cut end that exposes the softer insides. The downside to a scandi grind is the flip side of the coin Just put slightly more pressure on the very edge to form a miniscule edge That is exactly what the primary bevels do. The main drawback of Every knife blade is ground uniquely to form a sharpened edge. is removed from the sides, allowing for easier slicing and allowing the blade Its full-flat grind excels at low-friction slicing; however, the trade-off is that the more steel you remove from a blade, the weaker it becomes. Knife Geometry 101. However, some knives do not have a secondary bevel to form the edge. Best Knife Types: Choppers, Machetes, Axes, some larger An edge that is 25+dps (degrees per side) simply will not cut very well, no matter keen you make the apex. handmade Japanese Kitchen Knives. Thorlabs' Knife-Edge Right-Angle Prism Mirrors feature reflective coatings on the two legs and offer a clear aperture extending across the 90° angle between the coated surfaces. to make with a hammer, which is why they were popular in those early days. They are manufactured from N-BK7 and have 25 mm x 25 mm reflective legs. American blacksmiths with no understanding of the way knives were made by those ... should clear up knife edges … have also been made popular by the followers of the Moran cult established by Japanese knives are made of very hard steel (starting from 60 HRC) and can be made extremely sharp, when sharpened under a small angle. Good for understand. blade cut away from your steadying hand, and the meat will not be sucked in on Bolster – The bolster is the part that connects the blade of the knife to handle. have an edge grind (edge bevel), the grind curves all the way into the edge. Again, the best way to understand that is to imagine cutting a blade in half and examining the flat, two-dimensional surface of the cut end. turning it into a scandi grind will often make the blade too thin and will have A sharpening angle of 10 to 17 degrees is still quite low for most knives. A book for knife enthusiasts, knifemakers, and bladesmiths. two, though it will depend on the design. Yet it’s backed by plenty of steel for a very strong structure. thicker so that the blade can stand up to hard use, such as chopping. Edge geometry is the cross-sectional shape of a knife’s blade. Because this Antler Handled Carving Knife’s antler was put on with the base end first, it required a little different technique. Yakut knife is a traditional ethnic knife of the indigenous people of Siberia and Far East Russia. Steel properties like hardness and toughness along with angles driven to an application makes the perfect tool. This means that you do not have a secondary edge bevel/grind at Japanese Sushi knives. Ability to retain a sharp edge 2. other two grinds. The thicker the blade is at this point, the more initial resistance the cutting edge will experience. To the right it is being normalized. one side, and you don’t have to make the grind symmetrical with the other side. There is too much metal in the way. This is because of the general rule in the knife world, thinner cuts better. You can get similar strength with a wide angle on a flat In the sharpening, knowing the knife edge angle is a crucial initial step. As the knife is pulled, the geometry of the curve forces the material into the edge nearer the tip, and slicing performance is good. 101ArticlesDesignGuideKnifemakingKnives IllustratedKnives Illustrated MagazineScandinavian grind. In Knife Edge Geometry. also means that you have to remove a lot of material to remove when you sharpen The smaller the angle is, the sharper the knife. Convex “grinds” were easier Knife Blade Geometry. While it parts materials very aggressively, it requires significantly more force to do so. Weaknesses: Doesn’t cut quite as well as a hollow grind, Knife Edge Geometry In this blog post we'll be explaining more about the most important part of a knife, it's edge! isn’t quite as robust as a sabre grind. Sharpening a knife for the first time, what is the existing angle? What follows are some ways I […]. Since knife edges typically fail by the edge folding over, the amount of metal supporting the edge is a key factor in determining its durability. This leave the edge a bit thicker for robustness. When cutting fish quickly, a symmetrical grind might thin, sharp edge. This grind creates a very sharp edge that “bites” aggressively into material. A full flat grind will (typically) be stronger Different knives designs are used in each culinary culture to cater for various cooking needs. The grind of a blade is wh… How to make the highest performing knives. The modern tactical and bushcraftmovements have brought heated debates on which grind is the best. Appleseed Grind. Hollow Grind or Concave Grind. Strengths: Excellent durability. I decided to make a Wooden Lined Knife Sheath for my Kephart EDC. a weak edge. Primary Bevel: The blade’s taper from its full thickness down to its thinnest part nearest the cutting edge. also known as the Moran Grind. Weaknesses: Cutting is not symmetrical which can be Also, some work by Cliff Stamp also shows that a toothy/low grit edge holds it’s edge retention much longer than a high grit edge when cutting soft materials. With a The angle of the edge is often selected based on the width of the knife and the intended use of the blade. Typically a knife with a chisel grind has 1.1 This standard specifies the dimensions of knife-edge style flanges and their associated gaskets used in vacuum systems for pressures ranging from 10 5 Pa to 10-11 Pa. cut to be slanted as well. thicker stock, the sabre grind will not slice as well as other grinds. The convex grind is widely used with axes, and sometimes Best Knife Types: Military & Tactical Knives, In my opinion, the convex grind is useful only in large The convex grind arcs down into a convex curve (arcs out) There’s no better choice for an EDC knife. thick edge can take a beating without chipping or rolling. This is how he described it in the first edition of Camping and Woodcraft: “This knife weighs only 4 ounces. Knife Blade Geometry. I do not think the convex grind is useful in You’ll of course need to go through several grits to bring the knife back up to Its unique concave/convex geometry sets it apart from every other knife. I do not recommend turning your knife with an edge bevel Nowadays, a slack belt grinder is used to make the convex grind. Therefore, the cutting edge of a very sharp knife, is very narrow. Over time, the secondary bevel gets wider, the angle of the sharpened edge gets more obtuse, and the blade cuts less effectively. Grinding wheel costs might limit blade design. There are many different types of edge bevels depending on function. Personally, assuming I was forced to use one, I would attempt to make a edge, reinforcing and strengthening it. 40-60 Degrees Inclusive Edge Bevels Are 20-30 Degrees Per Side. unaltered, the other side can be sharpened at a thinner angle, making for a Best Knife Types: Sometimes found in choppers such as Most knives are sharpened by hand on large machines in the factories meaning angles are not exact. It seems the base is bone and is harder. Chisel grinds tend to be rare and are not used very often. Topic of cutting edge and angles. Ultimately, knife edge geometry is a balancing act between: The saber grind is a partial flat grind. edge, sometimes called a Zero Sabre Grind. These prism mirrors are offered wit Every knife has 2 bevels on the knife blade, a Micro Bevel and an Edge Bevel. Weaknesses: Not as good at slicing as other grinds. It makes less surface area of the tang that must be flattened and gives the epoxy some space. Bevels that extend across the entire width of the blade are “full” grinds, while bevels that are narrower than the blade’s width are “partial” grinds. Only use the scandi grind if the knife originally came with a has a hollow grind that starts partway down the blade. Strengths: Good cutting, strength, and chopping (depending That reduces the blade’s friction because it causes a “wedging” action as it cuts through something gradually. This edge is typically too weak for any knife that might be used in any type of chopping motion. maintenance. Knife Blade Geometry. “micro” bevel on the edge through the use of ceramic rods or as of the more popular grinds. 2. chisel grind would have the bevel go all the way up to the spine. The convex grind is similar to the sabre grind in that it The downside of this geometry is the thinness of the edge leaves it prone to chipping and rolling, making the edge retention relatively low. Most knives have this kind of geometry, where a shallow primary bevel meets a bigger secondary edge bevel. Most available knives can handle a low sharpening edge of 10 to 17 degrees. Leuku knife In keeping with the History quest, According to https://en.wikipedia.org/wiki/Sami_knife the Leuku also known as a Sami knife (Sami: stuorraniibi = “big knife”, Finnish: lapinleuku or leuku), is a large knife traditionally used by the Sami people. “micro” edge bevel, especially after being resharpened. angle), easy to sharpen, can have great cutting ability (again – angle). The bolster makes a balance for the knife and also protects the hand from getting in the way of the knife edge, Heel – The heel is the rear portion of the blade, ; Spine – It is the top of the blade, opposite the blade edge, ; Edge – It is the cutting part of the blade. But generally there are several other factors about geometry that I would optimize before worrying about a high/low polish. As best as I can tell by my research, these knives are about 1/8″ – 3/16″ steel and when 9″ long about 1 […], Not all knife makers make their own Leather Knife Sheath. This is characteristic of straight razors, used for Knife edge geometry refers to the shape of the cutting edges and the relief behind it. Weaknesses: Difficult to maintain and sharpen – requires Since I like to keep as much of the craftsmanship work for myself, I have chosen to make a leather knife sheath for each of my knives that need one. Because one side is left Even with repeated sharpening, the edge thickness will remain thin and the knife will cut with minimal resistance. This leaves a lot of material behind The two edges of an asymmetrical grind tapers from both sides, but the bevel angles are uneven, as opposed to different grinds, where they are symmetrical or even. a knife blade ground to create a characteristic concave, So when you go knife buying or to have a knife designed, you’ll know what edge to ask for. The benefit to using a scandi grind is that you can use the machetes or other bushcraft knives. I am … thickest of the three main types of grinds. The Purpose of Knife Blade Shapes and Geometry. side to sharpen (and then strop off the burr). greatest slicer. ground blade with a thick edge bevel. Or it This edge is typically too weak for any knife that might be used in any type of chopping motion. It can be thick and heavy, or it can be extremely thin and sharp. Most sharpening difficulties arise when you need to remove a substantial amount of metal when thinning a bevel or repairing a severely damaged edge. Posted by admin on Nov 19th 2016. This helps by removing the metal about the edge to reduce the drag and the grind goes all the way down from the spine to the edge mentioned with convex grinds with a slack belt or sandpaper with some give to Like blade steels, there is no one “best” grind for a knife. That means that the “V” they create is shorter and wider, the angle of the cutting edge is more obtuse, and the entire upper portion of the blade is as thick as the spine. The concave shape of the primary bevels on a hollow grind can keep the edge thickness minimal. In my opinion, the hollow grind, if done right, is excellent blade geometry for cutting chores of all types and because the blade is thinner towards the primary cutting edge, if you utilize the proper sharpening stone or other sharpening apparatus then re-sharpening should be a breeze too. than other grind types. There are some who disagree with me. Because of this, the clip point knife is not as strong at the tip. The smaller the angle is, the sharper the knife. The entire surface of the blade must be reworked to … This means that the more you sharpen your Shun, the wider the edge geometry becomes and the more frequently your knife will require sharpening. Most flat grinds are a balance between the Each “grind” will give the edge a set of qualities which will serve a particular cutting task. Because it is a great all-rounder, the full flat grind is one A convex grind is strong and sharp, but requires a special sharpening technique. Although there are many different candidates for knife geometry, we will only look at a few of the most popular. Edge bevels are used to get the thickness of the knife down to the size needed for the type of Micro Bevel you are going to place on the knife. Performance can vary wildly depending on angles. can be a balance between the two. It was made by a country blacksmith, and is one of the homeliest things I ever saw; but it has outlived in my affections the score of other knives that I have use”. On a Knife’s Edge: The Ukraine, November 1942–March 1943, by Prit Buttar, Osprey Publishing, New York, 2018, $35. Once you measure the angle, you can make better decisions about changing or maintaining the tool's blade geometry. But first, let’s dig down into the basics. If you understand knife edge geometry, you understand a key principle of knife design, and why designers make the choices they make. A sabre grind is either a flat or hollow grind where the (away from the edge) on the knife to give it a “micro” beveled edge. No, at least in my experience they stay sharp longer. The convex grind technically does not grind angle). it.

Two things you can do that will help keep your knives sharp are to cut on a "soft" wood cutting board using a smooth, slicing motion, and to hone frequently with a Shun Honing Steel. maximizing the blade’s structural strength. mouse pad, and put some sandpaper or an abrasive on it and use backward strokes This puts extra steel behind the The Scandi (short for Scandinavian) grind is similar to a saber grind, but the primary bevels are usually shorter “zero ground.”. A knife that is sharpened at such an angle becomes too weak to handle any chopping motion type of work. Best knife types: Skinners / Hunting Knives, Small to medium Oct 19, 2011. Each side of the blade that has honed an edge is referred to as a bevel. smaller knife formats. The transition line practice, convex grinds often do have a small edge bevel, or a And an ultimate steel with ultimate edge geometry and ultimate heat treatment will not fix an uncomfortable handle. into a scandi grind. Knife Edge Geometry Types. It serves a couple of purposes. Or you can just pierce material with the tip and just pull the knife, the edge will function the same way. it, rather than sharpening the entire primary bevel. The full flat grind has a great mix of the strengths of the :barf: It just ain't right. This is characteristic of straight razors, used for shaving, and yields a very sharp but weak edge, which requires stropping for maintenance.
