Heyas, I was suddenly struck with this idea for a lock while pretending to work in legal studies (A little bit of irony in that all I do in Legal Studies is learn about lock picking ^.^ , Ah well, as long as I'm not doing anything illegal and I'm learning about something usefull, I feel no shame ^^) I call it a "Double Sided Dimple Topped" Lock. Basically, it's a pin and tumbler lock with pins on both sides, and dimples on the top (so the keyway looks something like the most versatile tetris peice, you know, the wierd looking T)
Anyways, I tried making a diagram of the lock, but that fell through, so I whipped up a few images of what the key would look like to convey my idea.

Any feedback would be given a fonz style thumbs up

(the views of the key go as follow, Profile Front, Profile Left, Profile Above)
