Abstract
The present invention is a walking assist device which comprises a shaft having a hand grip at one end and having an end piece at the other. A retractable member is positioned within the end piece and has a point at one end. The retractable member may be positioned in a first position such that the point protrudes from the end piece. The retractable member has a second position in which the point is retracted within the end piece. In an alternate embodiment, a locking mechanism is connected between the shaft and the retractable member to provide an alternately locked position in either the retracted or protruding position of the point.
