Shomer-Tec's Titanium Escape Ring won't just serve as a symbol of your love for and commitment to your wife, it will also get you out of the handcuffs that chick from the hotel bar leaves you in after she Roofies you and steals your wallet.
The ring is cut from solid titanium bar stock and polished to a gleaming silver finish. Still, it's pretty unremarkable. On the outside. But a channel circling the the piece's interior houses a flexible saw and handcuff shim pick combo tool, able to open single-locked handcuffs, plus gnaw through zip-ties, disposable cuffs, duct tape, rope, and any other non-metallic materials that might sit at the center of your predicament.
Sure, if you're getting tied up during a robbery or kidnapping the aggressors could take your ring, thereby nullifying its usefulness as a means of escape. But...maybe if you ask nicely they won't.
