Talk about a rusty crusty wrench this one was. Its the first one I have seen in the wild so I had to pick it up. It has 2 screwdriver tips broke off and does have a file on the edge.
What is the butterfly looking hole for? wingnuts?

You have half of the tool. There is a mating half that has more functions. Marked Herkules Patent. Pictures will follow. We probably talked about them here before.

The blade is a hacksaw blade.

That is totally awesome had no idea. That explains the butterfly hole, thank you.

This is half of a Hercules bicycle plier tool.  Here's a link to a post on another tool website.  Our own Plierman posted the pics.

The other half of your tool is on eBay.

Found the other half today-never thought I would though.
Looks a lot better than the other.

What great luck!  Buy me a lottery ticket this week!

You might even be luckier than that. Check this out and send me a PM if interested:
