I have a Wave, a PST, a Crunch and recently gave a Blast as a gift. IMHO, I think the Wave is tops for the money. If money is not object, any of the Ti models would surely serve you well. The original PST does not have locking blades and does not have as tight a feel as later models. The Crunch is great but very limited in the number of tools it offers (toss in a Micra for the scissors if you go that route). The Blast is a bit large but offers locking blades, tons of tools and a fairly comfortable grip, all for about $50.
