Wow, those knives look terrific. Well done, OP.
My hobbies include going bicycling/walking interesting places, cooking/baking, reading books, playing board games, doing martial arts, writing stories, playing guitar, and collecting fairly low-cost artwork. I turned my interest in martial arts into a side hustle that has been good for me.
Mustachianism showed me that it was possible to do lots of activities I enjoy without paying an arm and a leg for everything.
