Leather working. I inherited my grandfather’s old hatchet and knife from when he was a boy scout, these 80+ year old relics had their original leather sheathes that were totally disintegrating and stiff. After looking fruitlessly for replacement sheathes I decided it couldn’t be that hard to make my own, and now I’m hooked. I have leather cases for all of my devices, leather bags for different traveling needs, and leather wallets and trinkets make the absolute best gifts. People are always blown away by hand made leather products.
