Abstract:
An ice screw comprises an elongated shaft with an external thread, and a bit with teeth. Each tooth has a cutting edge, and the bit is provided at a longitudinal end of the shaft. A notch is formed in bit at the base of each cutting edge in order to delimit a sharpening reserve of the associated tooth.
