>>This wallet pen idea is great. You put something useful in a handy unused space in your wallet (the fold) and it is always with you and it is not jumbling around in your front pocket. It doesn't even increase the bulk of the wallet. Now that's a good idea.<<<br><br>It is, I wish the execution were a little better. As I said, it's just two telescoping tubes (hard to describe), no mechanism. That's not a big problem, but when you show it to someone, they invariably pull the whole thing apart trying to "retract" it. It's also a fairly expensive solution, in Sterling silver. Still, if I lost it, I'd immediately order another.<br><br>>>Even better, a small magnesium firestarter like the Military Match from Done Right Manufacturing like Doug carries on a key ring would also fit in that space. Now you have a firestarter on hand even when you don't have your kit with you.<<<br><br>As I mentioned in another thread, I carry a P38 can opener in my wallet, and it makes an excellent striker, aside from opening cans.<br><br>I would think that model would be a little thick in most wallets. We know that the ferro-cerium (sp?) rods come as thin as one eighth inch (as in the Permanent Match, yet another thread), and there was a discussion in another forum where someone claimed to have replaced the blade in the Victorinox Swiss Army knife little screwdriver, the one that screws into the corkscrew, with a rod this thin. I find that sort of interesting- now you've got a knife and fire, the first two items on my list, in one package.<br><br><br>
