No idea what this is. Do you know?

[faribo]

An acquaintance of an acquaintance has this. No one knows what it is. I think maybe some sort of specialty hammer head?

Those cogs look they mated up with something else to form a ratcheting , winding, or grinding mechanism of some sort.

Interesting piece!

It's a carpet stretcher and laying tool. The blade is for smoothing and tucking carpet under door-sills, skirting boards and such, the multiple spikes are for gripping the carpet while it is stretched, the cup is for holding tacks, and the long spike would have fitted into a wooden handle. There's a patent for a very similar item here:

This is the one pictured in that old patent. The blade has a semi-circular notch, which I think would be useful for fitting carpets around pipework (although the patent says it's to assist the nailing of tacks). Yours is another and more modern variation, but you get the idea?

On another Site, this was identified as the cutting mechanism for an old Sheath Binder

I'm guessing it's a kitchen mallet/meat tenderizer/ice pick.

one of those multi funtional thig a majigs. no doubt homemade. put it aside u'll find a use for it someday

I'm going with the meat tenderizer guess. There are many different types that have a chopper blade. Is there a hole next to your thumb in the picture? I wonder if that would be for a wooden handle.
