This is a Petzl Quark. It has been used quite a bit. I've used it for about 4 years, both domestically and internationally. If there's anything specific you'd like to confirm, I can send additional photos. Please comment if you have any questions. -------------------- * Ice axe for technical mountaineering and ice climbing * Weight: 550g * Shaft length: 50cm * Materials: Aluminum, steel, fiber-reinforced plastic
