Tango, RATrun the Argentina branch of an ONG that also has an office in Perú, which is where I started working, we do a lot of outdoors work and I had a chance to meet some of the RAT folks in the Amazon rain forest. They walk the walk, that's for sure.
The RC-5 is a good knife, but it wouldn't be my choice for a hunting knife. It was designed by military SERE instructors and has some features that I don't like in a civilian outdoors knife. The blade is quite a bit thicker than regular RAT knives, and it's saber ground instead of full flat (i.e. the grind doesn't go all the way up to the spine). This makes it less efficient as a cutting tool (they went for strength, which makes sense for a survival knife). Then there's the pointy pommel, I hate those.
Take a look at the RC-4. Same materials, same great company, more hunting/woodsbumming friendly design.
Handles are made out of micarta, so there's no need to worry about blood, I've used my RC-3 (and my older RAT-3 from the Ontario era) to clean game quite often and have no complaints whatsoever.
