That’s something I’m still trying to figure out is the support thing. I been trying to figure out the indirect stuff right now. Watching jack crafty it looks really easy but, that’s of course not the case. Slowly getting better at it. Flint knapping is a very unique skill that’s going to take a lot longer than I thought it would. I think my old arthritic hands aren’t helping much either.. I’m still good but don’t have the dexterity or strength of my youth.
