Has anyone on here built their own practice dummy to fool around/try diff knife holds and practice on? I have seen a few pictures online of ones made from all wood to half wood & half PVC and even a tire on a stick. I refuse to pay $400+ for a piece of wood im going to stab and tear up when i can just get a few old tires and an old punching bag to make something with. I have pretty good DIY skills and can get ahold of just about any piece of equipment i need to build one. Any good forums out there or a good link to a cheap DIY dummy i can construct while i wait for my Fallkniven A1 to come in the mail
