Materials of the blade of Japanese knives

There are several requirements for kitchen knives’ material: good sharpness, toughness, wear(abrasive) resistance, and rust resistance.

What is the difference of knives?

Before I tried to explain the physical difference between Western and Japanese kitchen knives with below illustration.


…but I got further question from a friend:

a.Is the difference optically visible?

b.Is the actual sharpness different?

The guy said that he cannot be convinced that Japanese kitchen knives are great without clarifying those. If it cuts, it’s fine!

Yeah I agree with it. So here I try to show the difference from my viewpoint.
