Ok, so I just recieved a new rc-4 on monday through a trade, and it was the one with the molle back with the velcro, and the pommel cover thing to make it "jump proof". Well since I dont jump out of airplanes very often, I decided to make use of the space under the pommel cover for a micro firekit. I got 5 spark lite tinder tabs, and a 1/8" ferro rod cut to size to fit in the space. This will make a very compact emergency fire kit in that, If I have nothing but my knife, I will still be able to make fire. The new rc-4 is amazing as well, better sized for survival then my rc-6 imo.
