Types of knife grind
There are three main types of grinds on knives: hollow grind, flat grind, and convex grind.
Hollow Grind: A hollow grind is a type of knife blade that is ground creating a characteristic concave, beveled cutting edge. This grind is achieved by using a grinding wheel or a jig that is shaped to create the desired shape. The primary benefit of a hollow grind is that it creates a very sharp cutting edge that is less prone to dulling over time. The downside of a hollow grind is that it can be more fragile than other grinds, and more prone to chipping if not cared for properly. Additionally, because of the beveling, the edge may not be as strong as other grinds and may require more frequent sharpening.
Flat Grind: A flat grind is a type of knife blade that is ground to create a flat, straight cutting edge. This grind is achieved by using a grinding wheel or a jig that is shaped to create the desired shape. The primary benefit of a flat grind is that it creates a very strong edge that is less prone to chipping. Additionally, because of the flat edge, it may require less frequent sharpening than other grinds. The downside of a flat grind is that it is not as sharp as other types of grinds, so it may require more effort for slicing or cutting tasks. Additionally, because of the flat edge, it may be more prone to dulling if not cared for properly.
Convex Grind: A convex grind is a type of knife blade that is ground to create a curved cutting edge. This grind is achieved by using a grinding wheel or a jig that is shaped to create the desired shape. The primary benefit of a convex grind is that it creates a very strong, sharp cutting edge that can hold its edge for a long time. Additionally, because of the curved edge, it may require less frequent sharpening than other grinds. The downside of a convex grind is that it can be more difficult to sharpen than other grinds, and may require a professional sharpener. Additionally, because of the curved edge, it may not be as suitable for certain cutting tasks.
Other popular grinds.
Scandi grind on knives is a type of blade grind popularized by Scandinavian knife makers. It is a simple grind that is easy to produce, making it one of the most popular grinds for knife makers. The scandi grind is characterized by a flat bevel that runs along the entire length of the blade, resulting in a sharp, even cutting edge. The angle of the bevel is usually between 15 and 25 degrees, depending on the type of knife and its intended use. The flat bevel is usually paired with a convex secondary bevel for additional strength and durability.The scandi grind is popular for its balance between sharpness and durability. It is a great grind for outdoor knives that need to hold up to tough conditions, such as chopping wood or slicing through thick vegetation. The flat bevel ensures that the cutting edge is even and consistent, and the convex secondary bevel adds additional strength. The scandi grind is also popular for bushcraft and survival knives, as it provides a good balance between cutting ability and durability.The scandi grind is easy to sharpen and maintain. It is also relatively easy to produce, making it one of the most popular grinds for knife makers. The scandi grind is a great choice for outdoor knives and bushcraft knives, and it is a popular choice for high-end custom knives.
A sabre grind is a type of blade grind used on knives and other edged tools. It is characterized by a flat primary grind bevel that starts at the spine of the blade and ends at a point approximately halfway down the blade. The secondary grind, or edge bevel, is then applied to the remaining half of the blade. The sabre grind is often used on short, thick blades and is a good compromise between edge retention and ease of sharpening.
