Not sure if this is the right section but ill give it a shot.

I got a kaps firewallet around 2-3 months ago and the part that holds the wheel and the flint (the whole pole) broke off.

Any suggestions on fixing it? what type of glue?

I don't actually have one, but if the part that broke is metal, I'd suggest liquid weld or solder. That's the simplest metal-metal bond fix.
If it's a metal-fabric bond you want, try a dab of contact cement.

Awesome, thanks!
