The gun shop I was in last week had a similar but wallet size tool like that on the shelves for 2.99.
But it was just a small tool, no wallet like feature, and a lot less options on it - still for 2.99 and
fits in a wallet the size of a CC. Heck you can probably even fly with it - oh my.
yeah and if you walked through a metal detector every airport in the world would buzz in chorus. I'd kinda be scared of having my credit cards in there, what if I went to fix a railing and they all fell out?
