The Crag Hammer is made specifically for use in free climbing for removing chocks, fixed pegs, and placing rappel pitons. It has a long thin blunt pick that functions well for extracting nuts and cleaning dirt and vegetation from prospective nut placement cracks. It’s a very handy hammer in Yosemite where it is used along with a whisk broom for cleaning out dirty jam cracks. The Crag Hammer is extra light in weight and has a lightening notch under the anvil which helps the hammer to cruise securely in the holster. ("The Great Pacific Iron Works Catalogue," 1978)
