ABSTRACT:
A ski pole includes an elongated tubular shaft in which is slideably mounted a rod with a threadably retained pointed tip. A coil spring acting axially between the rod and shaft urges the rod to a position with the pointed end retracted. A handgrip portion of the shaft has an actuating button passing therethrough which projects axially from the rod. The pointed end is deployed by the depression of the button and a trigger pivotly mounted through the handgrip portion locks the rod with the point deployed by a wedging action.
