Alpine season is over--time for ice. So switch out your razor-sharp adze with the Black Diamond Standard Hammer. Unless you're planning on chopping a bivy ledge or clearing a horrendous amount of sun-baked ice, there's no reason to have any more sharp objects staring you in the face than is absolutely necessary. No longer will adze scars be a worry now that you're getting the Standard Hammer. *Fits any Black Diamond ice tools.
