NEW: marking knife prototype. I have made this handle years ago, maybe even 10 years ago and it's been laying around since then. I always liked how the design turned out and that's probably why I kept it around. Now, with the intention to expand the tool making more and more, it's time to put this to work. The plan is to make a few more knives to tweak the design. Once that is al done, they will be available for sale as a kit or custom made!
