ABSTRACT:
A saw blade has two portions that are adjustable relative to one another in order to vary the overall length of the saw blade. A hub portion includes a hub adapted to engage a saw. Opposite the hub is an engagement end. A blade portion carries cutting teeth. Opposite the teeth is an engagement end. The engagement end of the blade portion engages the engagement end of the hub portion. The engagement ends carry a releasable lock to hold them in engagement to form a saw blade of a particular length. To change the saw blade length, the lock is released, the engagement ends moved relative to one another, and the lock reengaged. A locking sleeve can be slid to enclose the engagement portions to more securely hold them in engagement.
