Knife Blades 101

Flat ground

A straight line from the edge to the spine creates a wedge-shaped blade that offers a good

compromise between cutting ability and durability.

Hollow ground

A concave shape leaves the blade edge very thin, making it easier to sharpen (but less durable).

Chisel ground

Only ground on one side; it’s inexpensive and allows a folded blade to rest flush against a nonenclosed handle—without causing a safety hazard.
