I do have an Exacto knife (somewhere), and should give that a try, but with my old Dupuytren's hands, I find it difficult to work with thinner tools. I need thicker tools, probably thicker than the wooden handled one this gentleman uses, in fact. Another reason I want to get a feel for the tool before purchase. Amazon has some ergonomic Xacto knives from which to choose. I may try one of them. Thanks for the idea, navigator9.
