Abstract
A blade-replaceable saw is provided which enables blade replacement work without the need of an additional connecting fitting or the like, facilitates extraction and insertion of saw blades with respect to the grip during that work, and also prevents looseness between the saw blade and the grip even during the use of the saw. The blade-replaceable saw has a saw blade (10) and a grip (20), the saw blade (10) having on its base side a flat insertion handle section (12) configured to be inserted into the grip (20), the grip (20) having a flat insertion slot (22) for receiving the insertion handle section (12) of the saw blade (10), the saw enabling replacement of the saw blade (10). A projection (24) is formed on an inner wall surface (22a) of the flat insertion slot (22) of the grip (20), for reducing the contact area with, and also reducing the contact gap with, the flat insertion handle section (12) of the saw blade (10).
