Abstract
The ski pole has normal strength when the pole is normally gripped at its handle and reduced strength when not gripped. The poles permanently deform when a predetermined level of excessive bending force is applied. The pole shaft is hollow with a short circumferential segment having reduced cross-section. When the handle is gripped, a plug slideable within the shaft spans the reduced cross-section and reinforces the pole at that region. When the handle is not gripped, the plug slides away from the reduced wall segment and reduces pole strength. A button on the handle connects to the plug by a rod, cable, hydraulics, pneumatics, etc. Alternatively, button actuation electrically drives a magnetic solenoid to move the plug. The weakened portion is replaceable so the pole is reusable.
