I've been considering getting (yet another) knife. I can't afford custom-made, so it has to be off-the-shelf. The criteria I have is that it has to be large enough to be a decent chopper and handle batoning (i.e 6.5 to 7.5 inch blade). I also want it to be able to throw a spark off of flint, quartz etc., so no stainless steel. I've tentatively narrowed down to a BK-7 or Johnson potbelly, both of which are 1095 cro-van. My understanding is that this steel has a higher chromium content that regular 1095. Does anybody know how well this steel throws a spark? Thanks ahead of time for your responses.
