Technically I guess it is a Power Bass, which you'd think would be a little more rock n' roll.

I don't know that I have anything really obscure, although maybe one or two old wrenches that belonged to my grandfather or my dad would count. But the thing that really comes to mind is my Snap-On F50CSA driver handle.

I mean, it's Snap-On, so not really obscure, but that particular model has been discontinued and you can't buy them anymore, so it's a little bit obscure in that regard.

Anyway, it's a 3/8" drive driver handle with the socket cap in the head so it can be used as an extension. Those things are all over the place in 1/4" drive from every brand on the planet, but back in 1994 or so when I bought my F50CSA there weren't a lot of 3/8" drive ones around. Especially not the ones that could serve as an extension. There are more now, but they still aren't anywhere near as ubiquitous as the 1/4" drive ones.

Long story short, that tool is probably my favorite tool that I've ever bought. It's actually the only Snap-On item I own, as I consider their stuff too expensive to buy for the most part. Most of my hand tool collection is older (USA made era) Craftsman, with a smattering of other stuff. Lately I've started buying GearWrench, Icon, and Tekton stuff.

Funny you would mention that... I only recently (< 1 year's time) became aware of Wera. I bought myself some Wera screwdrivers earlier this year. And then I made the mistake of starting to watch Youtube "tool review" channels and discovered a whole slew of brands I wasn't familiar with previously. Now my bank balance is suffering some serious damage, but hey, at least I have some awesome tools.
