The FERROSTRIKE Super Socket V-4 is a 3 in 1 super bush tool that's a must have for your EDC pouch and emergency supply gear. The machined sharp edge allows for generous spark production when raked against a ferrocerium rod. The apposing flat edge works very well as a spark producer when struck with a piece of English Flint rock and then of course the bow drill socket performs very well for stabilizing the spindle for primitive, bow-drill friction fire technique. The 3/8" socket hole reduces friction and heat while bowing.
