Abstract:

A hammer with concealed adjustable fulcrum having a pivot region recess in the head, a tab slide recess in the handle, and a shaft opening formed within the head and handle. An extension rod with distal end shaped to form a rocker plate capable of flush recession within the pivot region opening is slidably adjustable within the shaft opening. Single-handed manual depression of a release tab bends a spring steel tab into the shaft opening to slide a T-clip out of a T-guide recess opening for slidable adjustment of the rod and rocker plate to one of a plurality of possible positions. Conversely, manual release of the tab causes the spring steel tab to bend towards the tab slide region thereby inserting the T-clip into a T-guide recess to lock the rod and corresponding rocker plate into a desired position.
