Abstract
A hammer has a claw assembly that is linearly moveable relative to the head of the hammer so as to improve leverage and range of prying for nail removal. A locking mechanism secures the claw assembly in a position. The locking mechanism may be automatic or manual, and may comprise a ratcheting mechanism with a pawl and rack, or a clamping mechanism with a deflectable sleeve and engaged bar, or a biased pin lock mechanism.
