Claim Text:
1. An arrangement for monitoring the wear of a pair of hand pliers having crimping elements that can be pressed onto a workpiece, the arrangement, comprising: a data memory in which theoretical wear prognosis values Vt corresponding to dimensional changes of the crimping elements due to wear based on each actuation of the hand pliers at different degrees of crimping are stored, wherein the degree of crimping is defined by the distance between the crimping elements during actuation; means for detecting the actuation of the hand pliers and the degree of crimping; a computing unit configured to add up the associated theoretical wear prognosis values for each detected actuation and degree of crimping to arrive at a cumulative total wear value V; and a display unit configured to display a message if when the cumulative total wear value V reaches a defined threshold VG.
