My question is a very easy one: can leather scales be a reasonable option today? I know that back in the day some scales were made out of leather, and in the back of my mind leather could represent a nice media to work on. I was watching one of Magnus videos and saw where he kept his blades and I was thinking some engraved or tooled leather scales would look the part. Now my question would be what type of leather? Should I buy pre treated leather? How can I make it waterproof? Has anybody tried making scales with the stuff?
