So I wound up purchasing the Gerber Hinderer Rescue Knife. While the Benchmade did seem to be of higher quality, the Gerber is certainly good enough, and was substantially less expensive (I was able to purchase it for just under $40 using some credit I had around). Also, the oxygen cylendar wrench built in has already come in handy, so I think I made a good choice!

Initial impressions: The knife is tough. Locks up well, without any movement. Big thumbstud make it very easy to open. Seatbelt/clothing cutter went through a seatbelt like a hot knife through butter last weekend at an extrication drill. I also like the blunt tip on the main blade - I'd be much less hessitant to use this around skin than a knife with a sharp, pointy tip.

So far, I'd say it's good for what I purchased it for. I'll post a follow-up as I use it more.
