Imagine having to reach into a very tight, narrow space in order to grab something small. Ordinary grippers will be useless, but this unusual tool has its hinge placed way down at the end of a long bent arm from 3-1/2 to 8" long. The small mouth opens up 1/4" and will grab whatever you need to retrieve. You'll be mighty glad you have it. The set of all 3 will allow you to reach almost anything.
