The RC-5 (ESEE-5's original model!) initially came with a neat sheath. It also has that divit in the handle to use as a top bearing for a bow-style fire drill. I just carry a ferrocerrium 'fire steel' rod. It's Micarta grips are smaller - thinner.
The aftermarket Micarta grips that came with my BK-2 are thicker - and look/feel unfinished. The BK-2 slices & chops a bit easier - the slicker finish helps. The RC-5/ESEE-5 seems more refined. The BK-2 was bought for a 'Bug Out Bag'. Tough choice as to which I'd keep, if I could have only one. Naw, it'd be the RC-5!
