smalls - M'lady is an EMT, so for Christmas one year, I picked her up the Gerber Hinderer knife (
http://www.gerbergear.com/Tactical/Knives/Hinderer-Rescue-Knife_22-41534), and it's one of her favorite EMS tools - bar none.
The serrated blade is FANTASTIC for cutting fabric, latex, and other items - and she doesn't have to worry about "nicking" a patient with a Tanto blade, since the front nose is completely dulled (as in square-cut and rounded). Also, while it's a liner-lock, there is a "switch" on the SIDE of the knife that retracts the liner to close the blade - so you don't have to put your finger in the path of the blade (which may or may not be contaminated) as well as beign MUCH easier to close with gloves on.
The 02 wrench (which is INDISPENSABLE for an EMT, by the way) is her favorite part of the knife - since 02 wrenches are often lost or stolen on most trucks, having one she can keep with her has been a saving grace. The plastic handle around the O2 wrench cut-out is chewed up - but the working surface (part of the metal frame beneath the plastic) is still flawless - and I understand she still uses it frequently.
The belt/fabric cutter on the end is pretty sharp - she's gone through a few patient's clothes with it and not had too much of an issue. It's easy to open and easy to close, and although it's a squared edge (vs a crescent edge found on most belt/fabric cutters), it tends to cut pretty well.
Lastly, the butt on the knife features a keyring hole big enough to fit Paracord through, and a GLASS CUTTER at the end. It's not a diesel 3/8" glass cutter, more like a .177" mini-stud, but I'm sure with a good whack it'll go through glass no problem.
Side note - the knife also comes with a L-shaped adapter and a small socket and driver set. I don't know if she still has these items kicking around, but it's about the only "unnecessary" part of the knife kit.
SO, from someone that has gone through the "what knife should I get an EMT?" experience, I can COMPLETELY recommend the Gerber Hinderer Rescue - and believe me, I've been through EVERYTHING that Boker, CRKT, Ka-Bar, and the rest of the $40-120 knife-makers offer.
