Ah, yes -- Crux does like the Para 3.
I don't see the Para 3 as an "improvement" on the PM 2 -- it is another knife. The name is truly unfortunate because it leads to so many misunderstandings. You could call it a variation, and indeed many people adore it. I am not one of them, I prefer the PM2.
But the Para 3 is a nice knife. I have one in Cruwear -- that steel was enough to finally push me over the line to buying a Para 3.
And I am glad to have one, especially in Cruwear. All things have their time and place.
It is great that so many are nuts about the Para 3 -- good for them and good for Spyderco. For me though, owning the Para 3 just makes me appreciate the PM2 all the more.
