Specifically, it is an object of the invention to provide an improved saw including improved co-operable adjusting means on the handle and the blade thereof accommodating rapid adjustment of the blade on the handle to any one of a plurality of positions, in each of which positions the blade is securely mounted on the handle. Another object of the invention is the provision of an improved adjustable saw of highly economical construction. A further object of the invention is the provision of an improved adjustable saw wherein the co-operable adjusting means on the blade and handle are formed directly on the blade and handle as part of the normal process of making blades and handles and without necessitating special manufacturing and assembly steps. A still further object of the invention is to provide an improved adjustable saw wherein the co-operable adjusting means on the handle and the blade are formed along abutting edge portions of the handle and blade. According to the invention, my improved adjustable saw includes a handle comprising a metallic casting, which is cast to define directly a blade mounting surface, a shoulder defining one edge of the blade mounting surface and locking portions in said shoulder, and a blade comprising a metal stamping having locking portions stamped in one edge thereof which are complemental to and co-operable with the locking portions on the handle. Since the said locking portions are formed, respectively, solely by casting and stamping in the usual or customary manufacturing steps of casting and stamping, the same are obtained, in effect, free of cost, thus to afford a highly economical saw. Further, the disposition of the locking portions in abutting edge portions of the handle and blade affords a structure wherein the locking portions are not subjected to bending stresses and are adapted to support loads applied thereto in an optimum manner.
