Hey Mark, I use pin vises from knives as well. I used some epoxy to glue on Super magnets from home Depot, they fit the bottom of a heavy duty Friskas knife exactly. I then use any metal or decking plates (4 bucks at depot) and place them anywhere. I put sockets into pvc plumbing attachments and slid it on a rotisserie, handles fit right in. The system is flawless and works perfectly. I do 30 to 50 baits this way every week. Never an issue. I'll add pic's if I figure out how to!
