My Magic Hook & Eye

Is anybody else as clasp challenged as I am? It doesn't matter whether it's a hook, a lobster clasp or a toggle, I have trouble doing them up on myself, especially on a bracelet, where you only have one hand to work with. For every hour of wearing, I usually have ten minutes of cursing, as I try to do them up.
BUT!!! I have discovered a magic clasp! Dunno if it'll work on anything other than my cuff because of the placement of the loop, but I'm sure a loop can be worked into most designs.

Looks simple, doesn't it? Aha, but the secret is the little whorls on each side of the clasp. Just perfect for big clumsy thumbs to press. By pressing on the whorls with your thumb, you hold the hook in place and provide leverage while you slide it into the eye. It's like a hook with v-i-a-g r a. (I have spelled that out so my blog doesn't get ads for the same. Hope it works). Nice stiff hook that you don't have to embed in your arm trying to get it into the eye. Tres simple, n'est pas? I'd like to take credit for inventing it, but I'm sure someone has used the same principle somewhere, somehow. I forgot to mention the magic hook and eye with the Oh Be Joyful cuff, but this way I get to do two blog posts. Bonus.
