Hey Benjammin, great review. From what you've said, the Mule looks like a good choice for a heavy duty folder. Any way to get the hinge open a little easier? Maybe you could loosen the front screw a bit if possible. I did this with another folder that was really stiff. It instantly solved the problem though it might not be so in this case if the lockback is producing so much friction.
Is the false edge on the clip point just cosmetic or is it actually sharp/sharpenable? Not that it's a big deal but I personally like to sharpen the clip point on Bowie-style blades (like my fixed blade USMC Kabar).
