An object of the present invention is to provide a replaceable-blade-type saw in which a handle fitting part can be insertably engaged in a guide member even if the width dimension of the handle fitting part is greater than the width dimension of the guide member. In a handle fitting part 3 of a saw blade 1 is formed a slit part 8, which is configured from a first slit part 6 formed inward from the side edge part of the handle fitting part 3, and a second slit part 7 formed as a continuation of the first slit part 6 as well as being formed toward the distal end side of the handle fitting part 3 from an inner end part 6A of the first slit part 6, and a slit outer-side part 9 positioned on the outer side of the slit part 8 of the handle fitting part 3 is elastically moved or elastically deformed inward by the slit part 8 when bearing external force exerted inward from the side-edge-part side.
