A hand guard for a hacksaw has main portions extending outwardly and rearwardly from a rear post of the hacksaw frame and top and bottom portions smoothly connecting upper and lower regions of the main portions with upper and lower regions of the rear post. The guard forms a cup-like receptacle for the fingers and knuckles of the hand of the user to protect them from contact with foreign objects. The top portions of the guard have depressions therein for receiving the thumb of the user in a comfortable extended position.
