What could I do with my psk for footwear?

The wire-saw could be used to form foot sized planks from a small log. The Xacto blade could drill out holes for paracord to turn this into a flip-flop type sandal. With a pair of holes at the front between big toe and next and a pair of holes at the side of the heal you could even fashion something that would adequately grip the heel. Not sure I would have enough paracord for that though. A little of work on my pants would liberate enough extra strips of cord to finish the sandal straps. The wooden soles would not be too great for traction but would provide real good protection from ground debris. If I were walking over pebbles, nettles, prikly-pear or blackberry or like areas I would want the sole protection.

Something similar to this sandal wouldn't be too hard to fashion. If I wanted something with a bit more flexibility I would try to find an old tire or get a large piece of leather or rubber. An old tire with decent tread would be optimal.

This line of thought is really got me intrigued. I may try to fashion a pair of these just for the exercise. This might be considered essential primitive / urban survival skill.
