Just really started getting into J-knives recently, and been looking at what to purchase. One thing that I'm not really clear on is initial sharpening. From my reading, I understand that if I buy a knife from Japanese makers directly, initial sharpening needs to be done to remove the factory edge to unlock the potential of a knife. A couple of questions comes to mind:
1. If I buy a knife from someone like Tosho or JKI, does it still need initial sharpening? I.e. do these retailers do the initial sharpening by default?
2. How about if I order from Aframe or MetalMaster?
3. How to tell a if knife needs initial sharpening?
