<p>In a folding saw in which either the edge of the blade, the handle or both are curved, to prevent the edge of the blade from being exposed when blade is folded so that the saw can be handled safely. <H0> (Means of solution) </H0> A protective cover (4) in which the edge (1a) of the blade (1) can be nestled is placed inside the housing groove (3) of the handle (2) having a semi-U-shaped cross section for housing the blade (1) in such a way that it is pivotally revolvable around the top end of the handle. A revolvable control lever (5) is established at the bottom end of the handle (2), and a portion of the control lever (5) is engaged with the tip of the protective cover (4). The protective cover (4) can be retracted into and pulled out of the housing groove (3) of the handle (2) by the revolving operation of the control lever (5). In this way, the protective cover (4) covers the edge (1a) of the blade (1) that is exposed from the housing groove (3). <IMAGE></p> |
