I don't own any, but I have used some tiny ferro rods in the past. The best route to go with them is to use a stick behind them (and cut a small notch to steady it in the stick) and then hold on to both and pull it toward you under your striker.
I received one with a sak I picked up but never used it and probably never will. They should have made them to fit the pen slot on the plus scales, at least then it would be bigger!
I got an email from these folks this am about a new offering, a corkscrew twist-in ferro rod and possibly tinder. Might be better carry than the questionable toothpick slot.Could not find it on their website but it said tomorrow announcement.
