Abstract
The present invention entails a cane having a finger assembly in the lower portion thereof and extendable from the cane for gripping objects. In particular, the finger assembly is biased toward an extended position. A locking mechanism enables the finger assembly to be locked in an infinite number of positions between a fully extended position and a fully retracted position such that objects of various sizes can be retrieved and held.
