Spent 2 years using my bone folder backwards, a bookbinder in Ohio set me straight
I was at a workshop in Dayton last month and this older guy watches me crease a signature and just laughs. He points out that the smooth side of my bone folder should be doing the work, and I've been using the curved edge this whole time. Turns out every fold I ever made had a tiny ridge in it that I never noticed. Has anyone else had a tool revelation that made you question your whole setup?
