Well, I've handled a few Blurs, a Manix or two, and I own a Paramilitary 2.
Beyond that, the PM2 tends to draw from the best of all worlds. Its not quite the tank the manix is, and it's not quite as slim as the blur, but it has the strongest, simplest lock between the three, same steel as both, and an excellent blade shape and deployment method. It can't pry like a manix could, but that's not what a knife it's for. If you need something cut, the PM2 is your best bet.
In other words, the Paramilitary 2 is the do anything knife which is amazingly light for what it offers. Don't pry, don't abuse the tip, and it will make any justifications for buying other knives much tougher to find.
