How it's used

Refers specifically to the sharpened cutting part of a blade rather than the entire tool. While it can be used for kitchen knives, it is also frequently used in metaphorical contexts to describe the sharpness or precision of an argument or a situation.

Examples

The edge of this knife is very sharp, be careful.
Have you finished sharpening the edge of the knife yet?

Common phrases

sharp blade edge
sharpen the blade edge

Common mistake

Do not confuse this with 刀口, which is more commonly used in mainland Mandarin contexts; in Cantonese, 刀鋒 is the standard term for the edge of a blade.
