I rate that idea at a 7 out of ten with eight being the highest. Oh, wait, inside joke from CMW 03, noone’s gonna remember…
Seriously, it’d be cool if it worked, but one problem is that a lot of grinds are on polished metal which won’t spark very much.
On the other end of the safety spectrum, you could have a 3 part grind plate. The front of the plate is magnesium with a rough surface, the middle is flint, and the back is more magnesium. THe front would scapre powder off on the obstacle, whihc the flint would then ignite, which would further ignite the back magnesium. Flaming pedals .
i though of that, but i think the flint is going to give tou more sparking plus i think the mag. is going to need to heat up more before you starting having flames
