Tod's Workshop made a reproduction of a curious hammer with a longsword handle, which had some limitation which might explain why they weren't popular, the source being a one-of-a-kind example in a British museum.

But the Real Armeria de Madrid, which is poorly known since they forbid pictures and is in the Iberian Peninsula, has a "hammer of arms" attributed to John of Austria, under the reference H.10, dated c. 1550-1575. Carl Koppeschaa took the following pictures, and own the copyrights.

It's different from Tod's reproduction because it's the handle and body of a hammer with a longsword blade instead of a spike, being perhaps way more useful.

Is that blade actually retractable? The metal haft of the hammer looks too thick not to be hollow, and there even seems to be a hinged cap on top of the hammer head to neatly close the opening when the blade is retracted...

Mikko,

Great catch! Thanks to Pedro's posting and your sharp eyes, what I would assume to be a very rare weapon, is getting some attention.

The spotlight article on combination weapons shows two other hammers (and one pollaxe) with such hidden blades extending out the front, BTW, one of them very similar to this one.
