Definitely going to be making one of these. I work at Leatherman Tool and everyone will get a kick out of it.

One thing about your design. On the blade lock, normally the end edge of the knife is cut/ground at an angle instead of 90º to the flat of the blade. What this does is give the locking tab a ramp to wedge against. In a perfect world, a perfect flat edge against a perfect flat edge will have no wobble, but in the rear world, it's very difficult if not impossible to make. By making the end at an angle though, the locking tab just moves until it can't anymore (wedges) and makes for no wiggle in the blade.



I hope I explained this clearly enough. Look at the end of your black knife. I bet it has an angle on it. That's how we do it at Leatherman anyway.
