I was asking about the triangular dicoloration of the part of the lockbar, at the end (inside), that I thought was getting polished and discolored by my new and STIFF Sebenza. I found out it was where Chris fire hardens it with a piece of tape or something on it and it leave a shiny spot when the foil or tape is removed. It was in a post from 2007, I should have left the post up and put the link in there for others to read.
