My top five? That's tough. I'll need to post them one at a time, while I think about my answers.

Here's one of them:

Busse Pepper Shaker

That's been my EDC for several years now. It's the smallest Busse made, as far as I know... I hardly notice that I'm wearing it. Super thin geometry cuts like a laser beam, but it still shrugs at very heavy duty use. Cool looking, too.
