Tonight I have been messing with a file and a zwickey two blade. I sharpened the head front to back going lighter with the pressure as I finished. Here is my question. The edge seems to have a visable burr on the edge. The edge does not really shave good, but when I run it across my thumb it just feels like it is pulling/grabbing and lays the skin open with little pressure. Is this the edge Mr. Bear preferred and is what I am calling a visible burr what is actually tearing my thumb up? I hope you guys can follow my description. The edge actually seems pretty lethal.
