Knife edges come in all different styles. We break down the major types in this quick guide to blade grinds.

Cutting performance is greatly influenced by the way in which the maker grinds the knife. Each grind will have different cutting characteristics. A good knifemaker will consider whether the grind of the knife is suited to the chosen task. You as a buyer will also need to consider if the grind of a knife will suit the tasks you have in mind.

Flat Grind

A flat-ground knife is a simple wedge and may be thick or thin. Flat grinds are good for slicing and deep cuts. I personally prefer a flat grind that goes all the way to the spine. A thinner flat grind will cut more smoothly than a thicker flat grind, where a thicker grind may be more durable.

Hollow Grind

A hollow-ground knife has a slightly concave bevel, which makes it thinner behind the cutting edge. This makes for good skinning and shallow cut work, without giving up overall blade heft or durability. Deep cuts or chopping are not well suited to a hollow grind.

Convex Grind

Convex grinds have slightly rounded bevels, which increases their edge stability. While they may not excel at slicing, they’re the way to go for hard use cutting and chopping.

Scandi Grind

Scandi grinds are a short flat grind with no secondary bevel. “Scandi” refers to the Scandinavian countries where that grind style is popular, especially Finland. This grind style cuts very well but can be difficult to sharpen properly.

Compound Grind

A compound grind may combine several of the basic grind shapes. Particularly on tactical and folding knives, many modern grinds are aesthetically interesting, but at the occasional sacrifice of performance. If you’re collecting for aesthetic reasons, however, these grinds could be all you ever wanted out of a knife.
