I'm having a problem with my gerber ghost strike. Have been carrying it scout carry. Problem is I sharpen it on my sharp maker to the point it can push cut paper and slice phone book paper. When I take it out of the sheath the edge does rub the sheath some but would think it would cause instant dullness. It won't even slice paper after I take it out a time or two. I could change the carry to where it doesn't rub but I'm thinking there is more too this. Could it be that there is possibly a micro burr still left that I can't see? How do I fix this?
