ABSTRACT:
A foldable saw includes an elongated handle member having opposite side walls which confine a slit therebetween and a top wall which bridges the side walls. A saw blade is formed as an elongated flat plate with a teethed edge, and has a rounded end portion mounted pivotally on the handle member such that the saw blade is pivotable between folded and unfolded positions. A locking unit is mounted on the handle member and is operable so as to engage releasably the rounded end portion of the saw blade to lock the saw blade in a selected one of the folded and unfolded positions. The saw blade has an indented section located between the rounded end portion and the teethed edge. The top wall of the handle member is formed with a through hole which extends to the slit and which is aligned with the indented section of the saw blade when the saw blade is in the folded position. The through hole has a release spring disposed therein, and further has an internally threaded upper section which engages an externally threaded plug that abuts against the release spring. The release spring is compressed by the saw blade when the saw blade is locked by the locking unit in the folded position, and expands to cause a tip of the saw blade to project out of the slit of the handle member when the locking unit is operated to unlock the saw blade from the folded position.
