As Papaw pointed out in another post, this may be more of a "why's it", than a "whats it".
This one is based on a meat cleaver, and on the end are a bunch of things that can be rotated into position for use.
I found a hammer, alligator wrench, ice chipper, meat tenderizer, can opener, and bottle opener. The only thing I see that is missing is a screwdriver, and I suppose in a pinch you could use one of the ice chipper tines for that.
Also the cleaver portion is for very light duty work, as the blade appears to be about half the thickness of a normal cleaver.
No makers mark...maybe nobody wanted to take credit for this thing.

I was going to make some far fetched claim for forgetting to post the pictures, but I'll just call it a brain fart and let it go at that. Thanks Papaw.
