The BIG STICK™ Flint is a large ferrocerium rod imported from Europe (This ferrocerium rod is not one of the Chinese rods and is harder than those. It provides very hot sparks, lasts longer, but does not provide molten gobs of metal). It measures 4" long by 3/8" in diameter. We have attached a 1" split-ring and one of our miniature snap swivel hooks for holding the striker when not in use. Some fire starters have a striker attached to a lanyard, which makes striking the ferrocerium rod awkward. Our attached snap swivel hook allows you to easily detach the striker for use, yet allows it to stay attached to the rod when not in use!
