I used to think a bone folder was just for creasing paper until a workshop in Chicago
For my first two years, I only used my bone folder for scoring folds, thinking that was its whole job. At a workshop last fall, the instructor showed us how to use the rounded end to burnish leather, smoothing out tiny wrinkles without any heat. I tried it on a calfskin cover project the next week and it cut my finishing time by almost half. Now I keep two on my bench, one for paper and one just for leather work. Has anyone else found a simple tool can do way more than you first thought?
