ABSTRACT:
A small hand tool such as a carpenter's hammer is disclosed as having a head which is pivotally connected crosswise to its handle. The head is provided with abutment faces which at different inclinations of the head to the handle are selectively aligned with the blunt end of a latch rod threadedly connected to the handle within a provided axially extending bore. Rotation of a larger-sized operating knob at the rearward end of the handle effectively advances and retracts the latch rod to releasably lock the hammer head to the handle in the selected position to which it is adjustable thereon.
