I have a small collection of chisels and assorted carving knives , hand tools etc. I plan on buying a set of gouges ,v-tool and u-gouge. How do you guys keep your carving tools sharp ??? I use a smith diamond stone , coarse and fine and then run it over some leather. I included a photo of some of my tools and I also use a dremel. What kinds of tools do you guys use most often to carve ???
