FWIW, I once threw River 8's Howling Rat at a tree. It bounced back and landed right in our campfire -- spraying coal and ash everywhere. I immediately went to action and fell to the ground laughing. The others, only slightly less amused, began to dig the HR out of the fire with sticks.
The Resiprene showed very little effect after being in the fire for easily 20 full seconds. A few of the cuts and marrs in the handle did seal up quite nicely. The only real burn marks where found on the knife's lanyard. <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />
Tough stuff! <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
