Abstract: A saw having an angle adjustable blade includes a handle and a blade. The handle includes a body and a ratchet structure. The ratchet structure includes a positioning member and a ratchet rod. Thus, the angle of the blade relative to the handle may be adjusted arbitrarily by rotating the blade relative to the handle, without having to change and adjust the angle of the handle, thereby facilitating the user operating the handle, and thereby preventing the user's wrist from being hurt.

Abstract: A screwdriver handle includes a front shank and a rear shank combined with each other. The receiving seat of the rear shank is formed with a plurality of receiving holes for receiving multiple screwdriver heads and sockets, thereby enhancing the storage space of the screwdriver handle. In addition, when one of the plurality of receiving holes of the rear shank aligns with the push block, the screwdriver head or the socket received in the respective receiving hole is pushed upward by the push block, thereby facilitating the user taking and using the screwdriver head or the socket. Further, the slideway of the rear shank has two closed ends to limit detachment of the guide rail of the front shank, thereby preventing the rear shank from detaching from the front shank.
