When I first started making boots, I dreaded skiving* the bottom of the top liners. I was using the green handled knife on the right; it was difficult and never looked good. Once I switched to the knife on the left, I suddenly became a great skiver and now it’s one of my favorite things to do. It only takes a minute now though.

*Skiving is using a knife to thin the edge of leather at an angle to a paper-thin thickness.
