An alpinist's best friend, Polar ice screw features an integrated crank and concave cut teeth for ease of placement in ice. The tube features a tapered profile for a smooth passage of the screw in ice. Polar ice screw is made from heat treated and hardened Chromoly alloy to achieve the desired mechanical properties.
