Spider-Fx / Ice-axe


The Innovation of "Spider-Fx"; is due to its hinge, which offers the user two new features. First of all it makes possible for the climber to carry out a powerful strike from the wrist, with the help of the new swing-function, based on the physical principle of radial acceleration. The climber remains close to the rock and uses his conventional technique but gains a more powerful strike. The second function offers the user a tool less change of the curvature of the axe whilst climbing. The rules that applies are as follows :;The steeper the route, the more pronounced the curvature of the axe will be.
