Not to hijack this thread (I have used lots of surfaces like the scales on your knife, but never that one - Lots of things work fine), but I would NOT use the survivaltopics.com method. The wax on the whole match will make it burn too fast (your fingers or you must drop it). Only wax (or use fingernail polish - most use the clear kind) on the top 1/3 or so. I use the old Boy Scout method of taking a strip of corrigated cardbord, placing matches in every second or third (keep the tips apart) corrigation and then dipping the group into the wax. If you want spares, dip the whole strip of cardboard in (most of the match will not get waxed) and carry the whole thing in a plastic bag. Then you have the match and good tinder together.

The best,

Jerry
