I guess I can't really say much,

However, the two Busse Kin knives that I bought both came really hair popping sharp. The RMD even had a slight mirror polish on the edge, it was really prominent at the very edge of the edge.

My FBM came with a slight shoulder rolled to the left. But even then, it would easily shave.
