Here we are going to discuss the blade grinds in knives and suggest some knives with these grinds that may be suitable for certain tasks!
What is a Knife Grind?
A knife grind is what makes the blade thin enough to cut with, it refers to the way in which the blade has been cut ready for it to be sharpened and polished . The thinner the blade is the more efficient the job will be, although it also means that the blade is more easily breakable. There are a variety of different grinds that all have different strengths, cutting abilities and sharpness retainment.
A blade with a hollow grind consists of a symmetric concave surface that ends in a thin sharp edge. This results in having a weaker edge meaning a hollow grind isn’t suitable to be used on firm, thick material. A popular knife that uses a hollow grind is the Anglo Arms 10.5″ Hunting Bowie Knife.
The benefits of this grind is that the blade does not increase in thickness as drastically as others making it extremely easy to sharpen. This makes this type of grind great for tasks that involve slicing like for preparation or hunting. However, due to being a thinner grind type the blade has less material supporting the edge, so is more likely to chip or damaged, therefore, hollow grinds aren’t good as large format knives like machetes as they are not the best for chopping.
A blade with a flat grind can either be high flat or full flat. A full flat grind has a bevel in a flat linear slope that goes down the spine edge. With it being the thickest at the spine- giving it more strength- and then tapering down into a thin edge for slicing, the blade grind is one of the most adaptable. The blade can pass more easily through material than some other grinds due to its primary bevel slope being straight and linearly. The Anglo Arms 10″ Rubber Handle Tanto Knife is an example of a high flat grind where a small portion of the blade is the same thickness as the spine before it begins tapering toward the edge.
The full flat grind’s benefits are that it is very versatile and is very good for chopping tasks. It is also one of the more stronger grinds. However, its doesn’t cut as well as hollow (but better then sabre) and isn’t as sturdy as a sabre grind (but sturdier then the hollow grind).
The convex grind gets its name from the curve that appears before it tapers off to the finest point of the cutting edge along the blade, giving the knife a really small edge bevel. This type of grind is similar to the sabre grind sit has a lot of steel in the middle of the blade making it stronger. The Anglo Arms St George’s Knights Lock Knife is a great example of as knife that uses a convex grind.
Blades with a convex grind are usually used with Axes or machetes and are most useful in a large blade which main role is chopping. However, the downside to this grind is that it is very difficult to maintain and sharpen.
Scandinavian Grind (V-Grind)
The Scandi grind (also known as a v- grind) is a thin blade with a short flat grind. This grind doesn’t actually have a secondary bevel instead the primary bevel is also the edge bevel. This therefore, leaves a lot of material which strengthen the overall blade. The Anglo Arms 20.75″ Wood Handle Kukri Machete is an example of a Scandi grind.
The benefits of the grind is that it is very easy to sharpen (although, the entire bevel has to be sharpened), the blade is also quite resistant to any chipping due to its strong edge. However, a knife that uses a Scandi blade isn’t as good at slicing as other blade grinds because the blade becomes dull much more easily.
The sabre grind has two bevel grinds, the secondary bevel is close to the edge of the knife and is the only bevel on the blade that needs to be sharpened. The primary bevel on a sabre grind does not cover the entire width of the blade, making some of the blade be unground. The blade will have a Sabre line which is the transition line between the ungrounds portion of the blade and the primary bevel. The Anglo Arms Tri-Coated Rainbow Lock Knife is an example of a knife that has a Sabre grind.
The benefits of this type of grind is that due to the dual bevel setup the blade gets a rough, thick edge which helps chipping and makes the edge of the blade much stronger. However, this grind is not recommended for fine detail work (like wood work) as it is not a single bevel all the way up. This also means that the grind is quite difficult to sharpen.
The chisel grind has only a single bevel on one side of the blade, the other side is completely flat. The bevel will start midway between the spine and the edge of the blade, it will then taper down in a straight line towards the edge. This will only happen on one side of the blade. A great example of a chisel grind is the Mora Carbon Steel Woodworking Chisel Knife.
This grind is easy to sharpen as only one side needs to be sharpened, due to one side being unaltered the other side can be sharpened at a thinner angle, creating a thin, sharp edge. The chisel grind is also good for chopping as well as cutting and is highly strong. The downside is that although it can cut well it does not cut accurately due to its unsymmetrical design, as well as that, the chisel grind requires a lot of maintenance because of it only having a single bevel.
