A hacksaw includes an elongated blade, a frame, and a blade tension adjustment mechanism. The blade tension adjustment mechanism includes a lever constructed and arranged to be pivotally moved between (1) a blade tensioning position so as to tension the blade, and (2) a blade releasing position so as to release the tension from the blade and thereby allow removal and replacement of the blade. A lock is slidably attached to the lever to slide between (1) a locked position wherein the lock secures the lever in the blade tensioning position, and (2) an unlocked position wherein the lock permits the lever to be pivoted between the blade tensioning position and the blade releasing position.

Une scie à métaux comprend une lame allongée, un cadre et un mécanisme de réglage de tension de la lame. Ce mécanisme comprend un levier fabriqué et disposé pour se déplacer en pivotant entre 1) une position de tension de lame, de façon à tendre la lame, et 2) une position de relâchement de la lame, de façon à relâcher la tension de la lame, et donc permettre le retrait et le remplacement de la lame. Un verrou est fixé par coulissement au levier pour coulisser entre 1) une position de verrouillage où le verrou fixe le levier dans la position de tension de la lame, et 2) une position de déblocage où le verrou permet au levier de pivoter entre la position de tension de la lame et sa position de libération.
