I never used a spinner, known that they exist for like 30 years, have had locks pick anti clockwise easy and not so easy in the more useful direction, but I always just ended up picking clockwise though it took more time, but now Im gonna make one, its middle of winter and looks like an in house project,
Some of those pictured have some square edges on the winder, thats why blood is spilled, those edges could be rounded and sanded and then they would still give a spanking but not so much laceration.
Comtech made his out of hard cheese, Parmesan is it?
is it possible to make this with interchangeable blades? a wide blade made of wide windshield wiper stock, and a smaller one, or a thing like a split tensor with a top and bottom of keyway grip, or a very short top of keyway version only? Im gonna find out.
excellent design, tshock, you got my vote in the next inventors poll.
I actually hadn't looked at this thread before, maybe I was waiting for it to go to 8 pages

Thanks for the design t man
