Can anyone help me locate a place online purchase ferrocerium rods? I'm looking for just the rods... no fancy handles or anything like that. A vendor with a variety of lengths and/or thicknesses (new word) would be great but I'm not going to be picky. I practice a lot with them using all types of natural tinder and I'm just getting a little tired of buying the cheap magnesium starters and other (more expensive) ferrocerium rod fire starters just to remove the rod and toss the magnesium bar or the handle portion. Any suggestions? Thanks!
