Yeah, I grabbed a Crow awhile back and was mostly impressed. Online it looks really flimsy, but I was surprised at how stout it felt in my hand. I guess the scales look like FRN in the photos and are aluminum in real life was the primary difference. The ergonomics were quite good also. The F&F was not super impressive, but, hey, it's a 20 dollar knife. The only thing I was dissapointed in was the liner lock. It locked up fine and reliably, no concerns there, but if I did a simple thumb flick about one in four times it stuck. It wasn't impossible to get out by any means, it just took quite a bit more effort than your hand expects from the other 30 times you had opened it.
But again, for 20 dollars, man, it's a pretty neat knife. Wish it were made in America though.
The Military is a gorgeous and super ergonomic knife, but dang, that thing is so long. I can't even imagine what your boss might do if he heard you were carrying a "military." I respect AllenC, but I would not carry the Military here in FW, and wouldn't dream of it in DC. My humble opinion.
The Yojimbo you might be able to pass off as a humble box cutter though, and its got a 3 inch S30V blade, great ergonomics (and well designed for SD, in my opinion) etc etc etc. It's about as long as the Military though handle wise, but again, I think you might be able to get away with higher ups eyeing it as its so box cutterish.
I'll go outside of the parameters, if you'll forgive me, and recommend a minigrip too. I think it's probably the best low end EDC out there.
