So I was trolling eBay and found this crazy looking old serrated wrench bike tool. The auction had no specifics. I can't think of what you would do with such an item. What the hell is it for?

1That's probably mainly intended as a locknut/cone wrench. Not capable of tightening something well, but can hold a flat nut well while you tighten against it. I'm thinking that variations of this were sold for servicing old bottom brackets, though I don't recall if they were the old cottered BBs or the one-piece units. – Daniel R Hicks Oct 31 '13 at 02:24

@DanielRHicks that makes more sense than the answer below. – Darth Egregious Oct 31 '13 at 12:00

It looks like a nice tool for rim bearings (15mm for MTB, 13mm for BMX front, 16mm for some MTB) – Alexander Oct 31 '13 at 22:10

It's a wrench that will work on a range of different size nuts and bolts. Each step on the top ramp will grab a different size. A further advantage is that it will work equally well (or badly) on four sided nuts, and on five and seven sided "security" bolts that a conventional adjustable wrench with parallel jaws will not work on.
It will not work especially well, but it's a one-piece equivalent to a proper adjustable wrench, which in turn will not work as well as a proper set of spanners. They're made because they're cheap, light, and easy to manufacture.
Edit: found the ad on ebay and it has another image:
Since it's only about 10cm long, it seems to be about 2mm thick based on the image above. So Daniel might be right, it would work for holding cones and locknuts in place. Wandering the internet I haven't been able to find anything similar, unfortunately, but I recall seeing them in some collections of very old tools.
