Saw these over on SSD, it's a seatbelt cutter that attaches to a pair of EMT shears-
Solidly in the "why the hell didn't I think of that?" category.
It just really caught my eye since I'm trying to figure out a good way to pack all the crap into this new fangled CLS bag the army issued me, including two pairs of those type of shears and a separate Benchmade safety knife. It would be pretty nice to just have one of those attached to the pair in the front tear-away pocket on the bag...
