Boarding axe.... in "Storia dell'arma bianca italiana" - Cesare Calamandre.

Many thanks, Dmitry.
That's exactly what I needed.

Thank you.

No problem. Glad to have been helpful.

I had an axe similar to that one construction-wise.
The head was a little bigger than the axes in Boarders Away.
I have seen them described on the internets as WWI Italian army corps of engineers axes or trench-making picks and such.
