It's probably not the best idea to plot a daring escape should you ever find yourself confined with a pair of handcuffs or plastic zip-ties. But if you and John Law don't get along, consider this clever Titanium Escape Ring that hides a small lockpick and saw. Just remember, the one thing it can't get you out of are the bonds of holy matrimony.
Available for just $69, the ring features an inner groove where you can stash an included serrated shim pick out of sight while it's worn on your finger. Of course, you won't be sawing through the bars of a holding cell with it, but zip-ties, duct tape, rope, and pretty much anything not made of metal is fair game. [Shomer-Tec via The Gadgeteer]
