I received a new strop for Xmas and I have some Chromium Oxide paste on it's way. I'm thinking of using my old English bridle leather board strop as the canvas for my new pasted strop. I have researched how to apply the paste (less is more) but how should I prep the leather on the board strop? I did make one nick in it learning how to strop (it was good advice to learn on it instead of an expensive hanging strop) so should I give it a good sanding first?
