So I have this knife I bought at a gun/knife show several years ago.  

I'm trying to find out if anyone else has seen any of these, if it's that collectible, what the value might be, and anything other information on these knives.  

I was told my a dealer, about six, seven years ago maybe?..., that these were part of a run of knives that Boeing had asked Surefire to make as emergency egress tools for helicopter pilots/crew.  It was designed as a tool to cut webbing, straps, but most importantly so I was told anyway, to make a hole in the aluminum skin of a helicopter body in case of a crash, to allow pilot and crew to escape the fuselage.  I was also told that @60+ were made, I can't remember but something like 64?  And that they were numbered, that Boeing never picked them up, and that they were released for sale to Surefire dealers and their customers.  This one was number 004, and I snapped it up.  Echos were going for $300.00 plus at the time, I've been out of the market, collecting due to health issues, but I've been going through some of my stuff and I'd forgotten about this item.  

Any help in any other knowledge, what it's worth, etc.  I'd appreciate, thank you ahead of time. Pics are below, I really like this one a lot.  

Doesn't sound like Boeing. No one would ever use a knife for egress, crash axe maybe. Having worked there for 11 plus years, I know their feelings on knives very well.

The A-10 has a tool that's attached to the inside rail of the canopy that's basically a knife with a 2" or so blade. It's sole purpose...to chop a hole in the canopy if you couldn't get out by any other means.

I can't offer any help but I doubt that knife would have been designed to cut a hole in a helicopter.  The blade style and tip is completely wrong for stabbing

This might help. Picture is no longer there but it was the same knife you have.

Yeah man, that's got to be it.  Mine is a chisel grind as well, and if I wanted something to cut through aluminum that's the grind I'd put on it.  

Not sure why they'd number them if not for T&E.  

Here is the pic he posted, google images still has it
