I make my own tools: mallets and head maul with nylon 3" (they aren't the best fot stamping), hole punch, some strap end punch, groovers, adjustable U and V gauge, edge bevelers, an adjustable creaser, an awl, a lacing-stitching pony, wood folders and wood slicking sticks, and my knives for cutting leather... my tools are "made at home", simple but working, only with steel, wood or brass, a Dremel, grinder, sandpaper and file. Now I'm making a strap cutter with my design and a new handle swivel knife with a lathe for metal tube. If you have a minimum of knowledge and some tools of carpentry, woodturner, plumber or blacksmith, everybody can do it. I assist sometimes to courses of do-it-youself, I look for the tutorials in a web site and I have read some book about.
