Sum'Tec Hammer Petzl


The SUM’TEC 43 is a very lightweight and compact hammer / ice axe that can be carried in a pack for use when needed, for hammering a piton back in, tightening an anchor, or as a second tool in an unexpected ice gulley. Its forged banana-shaped ALPIX pick and the new TRIGREST handrest (adjustable without a tool) ensure the performance required on technical sections.
