Thanks, I figured as much. Better safe than sorry, right?

I was more concerned with my Spyderco Swick (tiny piece of S30V) that got a big blast of the heatgun before I thought it through.

Not sure Kydex forming is for me anyway, it really is a PITA to get right it seems, especially fold over. Tried to sandwich knife between two pieces and got much better definition on the kydex, unfortunately they were scrap pieces and not nearly big enough to make a full size sheath for the S5.
