q1 - semi-automatic handcuff mechanism

Or another version that is stronger - modify the cutting blade to be a holding arc of a device like this:



You have the advantage of hooling the leg with the fixed part and then swinging the arc around to close the hook. With the hook closed, you have a great deal of control...

That is a good point, we had been looking at the issue from the perspective of coming straight at the leg, but hooking and closing gives an element of control i'd overlooked. I'll do some CAD (cardboard Aided Design) and see what I can come up with.

@others - pinching we figured wouldn't be an issue if the 2 halves of the cuff overlapped when closing (similar to proper handcuffs where the moving jaw passes between the leaves of the fixed jaw) - adapabilty in the catch size is needed because the size range of the pigs ranges from ~25kg (call it 55lbs) to over 300kg (~680lbs) but most around the 60-150kg range.

ideally we'd redesign the whole process to seperate the pigs and put them in a crush, but portability and size constraints prevent that.
