What edge angle to use on different knives

What edge angles to use is really subjective, because it is really a matter of personal preferences. The steeper angle the sharper edge, but it will also be more fragile. There is a few other things to take in to consideration though; how will the knife be used, the quality of the steel and blade thickness.

Western kitchen knives are traditionally of softer steel and take an edge angle of 19–23°, while Japanese kitchen knives are traditionally of harder steel and take an edge angle of 13–18°

Here are some rough guide lines, for what edge angle to use:

Thin flexible high quality slicing knives; thin fillet knives and roaster slicers that seldom touches the cutting board 13°

Thin high quality kitchen knives, that gets light use like slicing fish, meat and tomatoes and that needs to be extremely sharp 15°

Medium and heavy duty kitchen knives 18°- 23°

Very thick blades like cleavers 25°- 30°

Small thin pocket knives 20°

Medium pocket knives 23°

Big thick pocket knives 25°

Thin hunting knives 20°

Hunting knives 23°

Heavy duty hunting, camping and utility knives 25°- 30°
