I find that chromium-vanadium steel, while holding glimmer and shine through much abuse, is harder to hone to that razor-like edge that truly makes chopping a breeze (watch the fingers, please), merely mangling fine fruits and tomatoes, instead. (just tilt your head, thus) It's a tool best left for whacking at meat, as its heft and its strength make short work of bone; more cleaver than scalpel, if truth will be said. I've always preferred the high-carbon alloys, though now out of fashion in today's haute cuisine. While rusting and blackening with age - not the type you'd put on display - the blades stay as keen as the day they were minted, and wipe down nicely on sleeves.
