I have brought several products from Beaver Bushcraft by Mark Hordon and have tested them out enough to feel it was worth sharing them. I have a bearing block for a fire-bow that can also be used as a flint striker and pivot for a hand drill. I also have a striker that has been weaved onto paracord so I can use it instead of the back of a knife blade. Just makes it easier to put back in my pocket. The paracord is a reverse twist rope method and probably the ugliest join Ive ever done.
