I got my PPT yesterday and have been playing around with it. Its a pretty unique knife; very well-made and a neat design.
The liners seem to be steel. They have a cool matte finish and look like Ti, but theyre magnetic (and heavy, though theyre somewhat skeletonized). My sample weighs around 5.1 oz. total.
The lock-side liner is a little bit thicker than the Bradleys. Spring strength seems about the same as the Bradley, but the PPT is a lot easier to unlock: more of the lock bar is exposed on the PPT and its corners are rounded off.
Heres a pic with the lock-side scale off. You can see some of the holes to reduce weight (the other liner has them too). Theres a curved rectangular cutout at the bottom of the lock bar thats similar to the Bradleys. The square notch on the end of the handle is where the clip bends over.
Something else you can see in the pic is that theres a flat area on the scale. Thats where the bottom of the clip rests, so it doesnt snag or drag when you draw the knife from your pocket. Its a nice little detail. The edges of the scales are also chamfered, though you cant really tell from the pic.
Anyways, Im not sure how much Ill end up EDCing it, but its a definitely a sweet little knife. Congrats to the designers and makers. And thanks for posting here, Sacha! Those are some awesome knives. :thumbup:
