I'm in the same boat as you with the Para...it is a fabulous knife, but the handle is just massive and the blade's height takes up space...both of which make the knife also look larger than it is. It's great for heavier work and it really helps reduce grip fatigue when using it for long periods, but it's profile is simply large. A clip I got from STR made carrying mine
much more comfortable, but it is still too big for city/office carry. I'd love to see a 'Para Mini' at like 75% the size of the PM2 and a slimmer/shorter handle!
The weirdest thing of all, which I don't really get, though is the relative rarity of compact folders with form factors like the 707 or Sebenza. There is plenty of demand, but limited options. Larger/robust/thicker/heavier/overbuilt/etc. hard-use knives are great, but they do not fit the needs for someone looking for an EDC with characteristics of the 707 at all.
Ever consider grabbing one of the M390/blue/carbon fiber limited edition 707's? It's a sharp looking knife and in a color that is very rare for Benchmade to use (the shade is plain gorgeous.) And while I am not a big super steel fan, I must admit I've come to really like M390.
I really wish Benchmade would make more limited runs of the 707 (and the 705 when it was made.) The ones they have done are just beautiful works of art and hugely popular, and I really like how they have uniqueness for that top EDC, but they are so hard to find and secondary market prices go crazy high on them.
