Nothing like a bit of slamming jewelry to raise your confidence.

Ironically, however, it can also make you feel more vulnerable to thieves and attackers. How to even the score?

The Subtle Safety ring by Redstart Design doubles — or, shall we say, triples — as a mock knuckle ring. The three stacked sterling circlets unfold in a heartbeat to become a delicate but deadly-looking accessory. Though not intended for use as an actual weapon (don’t quit that Israeli self-defense class quite yet), it is a reminder to both you and the world that you’re a don’t-mess-with-me sort of woman.

And at $75 it’s a good deal, especially given that it’s two accessories in one: It folds back up again to become a handsome adornment for a single finger. Which in itself can make a powerful statement.

Sometimes a finger is worth a thousand words.
