Combine your keys with your multitool

This looks pretty awesome, but it’s difficult to say just how practical it is until you try it. I’m willing to do it, but first I need a nice Leatherman. The process looks surprisingly easy, assuming you have some sort of way of cutting hardened steel. You just use one of the multitool’s bits as a guide and then drill the right size hole — presto!

I think, personally, that’s better to go the other way and install a multi-tool on your keyring. I’ve had one of these things for a couple years and it’s gone through airports all over the world. Sharp as hell, never lets me down (though it has occasionally laid me open pretty badly). [via BoingBoing and MAKE]
