Damaged Boarding Axe?

[mgolab]

Thanks again Mark for the comments. I found the attached image, No. 42, on the right, from the old book Armouries in the Tower of London. I though it bears some resemblance.

I gently cleaned the axe up a bit and, interestingly, the cutting edge and spike, appear to be forge welded in steel. The rest of the head what appears to be iron.

Curious piece, in my opinion.
