Hello im trying to identify a hammer from a picture, the picture isnt very clear so i have made a drawing of it, i know its a poor picture but this is all im able to do.

The hammer comes from a "German picture" (sketch) that is around 300 years old.

Any idea of what this style of hammer is called or used for?.

Thanks for any help.

looks like a pyrolean mountaineering axe to me.

Exactly the same head shape from this side elevation as a Twybil

Whats a Twybil ?

It is a tool used for making mortice like joints in hurdlemaking, the axe end cuts the sides of the mortice and the sharp end may be chisel ended to pick out the centre of the to be finished mortice, the endsof the mortice are drilled and this tool remove the centre portion

The picture is not good enough to be definite but my best guess is a stone axe (NOT made of stone, for chipping stone). Twybills are normally much longer (on each end)
to reach into the mortises. It could also be a woodcarver's adze.

Looks like a rock hammer to me [you know the kind ,rock hounds use for breaking open rocks looking for fossils and such]......GOOD LUCK

Could it be a whitchakuzee rod attched to the Finagnal pin?

If this is the picture... it is for cutting files.....Kerry
