Cool! Old ice axes!
This one has a known history: it was my dad's. According to him (he's still alive, climbing, and turns 80 in March) it is a "Militar Diamond Point, Guide's Model." Diamond point refers to the shape of the pick, which also has teeth. He thinks "Guide" means it was extra heavy for chopping steps. It certainly is extra heavy. Also very long because Dad is 6'4". Dad bought it in 1946 from Darr's Mountain Shop on Mount Hood.
The text under the lion on the ice axe says "Garantiert." (guaranteed in German?)
Note the screwed-on stop-ring for the strap and the one-piece forged point.
