lol, yep knots are free. My interest is in the workings of the jaw design. Because it is based on compound fulcrum and lever, the grip strength need not be a static factor, in other words it can be changed with a little tinkering (easier to open - even under the increased load of beefier bands) and with the addition of a catch mechanism it can be loaded, opened and locked into position (making it faster and easier to get on a bag. I'm thinking this will turn out in my favor, won't know till I try. Plus, I'm originally from Missouri, that show-me place....
Thanks everyone for the feedback.
