Never had a Para 1 or 2, but the way people always talk about how functional, solid, and practical it is always reminds me of my ZT 350. I want to get a PM2 just to compare the two. The ZT 350 is my favorite EDC of all time right now, my Benchmade Griptilian is a close second.. but soon that will probably change, the 350s big brother is about to join my EDC line up. I may have to pick up a PM2 after the holidays, just to try it out. I also have a Manix 2 in Translucent Blue on the way, so if that doesnt work out Ill probably replace it with a PM2.
I really dont see the PM2 replacing my ZTs though, especially not the ZT 350, its thin and light enough to be amazingly comfortable but thick and strong enough to feel like a tank and handle whatever job you need it to do. But with that said, I like to carry two knives at all times (except maybe at work, two knives is kind of overkill when youre in formal wear) a nice slim, light, slicer like the Griptilian 550HG or Manix 2 and a heavier, more solid, much tougher monster like the ZT 350 or ZT 303. I had been doing this at work using both my ZT 350SW and a BM Mini Bone Collector (Recently Traded) but I only ever used my ZT, but outside of work I ALWAYS have two knives. So if I do get a PM2 it wont replace any of my ZTs, it will just ride with one of them.
