<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, 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. The protective cover 4 is retractable with respect to the housing groove 3, and when the blade is folded, projects out of the housing groove 3 and covers the edge 1a, which may be exposed. The protective cover 4 is preferably energized by a spring so that it covers the edge 1a whenever the blade is folded. <IMAGE></p> |
