• Made in France [ca. 2015].
• 265x95 mm.
• Weight: 550 g.
• Steel Shaft with Rubber Grip.
• Shaft: 18 mm. (Grip: 33x24 mm.)
• Fixed head with carabiner hole.
• Hammer: 30(l)x30(w)x31(h) mm.
• Hammer head.
• Piton pick with a hook for piton removal and with 1 ventral teeth.
• Pick: 33(l)x24(h)x9(t) mm.
• Wrist loop tied to ring around shaft.
• Archetypical standard hammer for Euro-speleological bolting.
• Handle equipped with a 13 mm socket to fit 8 mm bolt heads. In a pinch, this can also be used on 1/2 in. Freedon Unit bolt heads.
• While having a built-in wrench may seem handy, the restriction to a single size unrealistically assumes that every bolt in every situation will have the same size head. I've always preferred carrying the proper sized open-end wrench as the proper tool for the appropriately-sized bolts that I placed.
