Abstract
A versatile saw that can be used as a high-branch-pruning saw, etc., employing an annular internal toothed saw disk having internal teeth on its internal circumference. Each of a pair of openable holders support the periphery of an annular two-piece internal toothed saw disk and maintain the internal toothed saw disk in an annular form with the holders closed. An object is cut by the internal teeth by rotating the internal toothed saw disk maintained in an annular shape while being held by the holders along its periphery. The rotating internal toothed saw disk is capable of stopping at a prescribed position of the holder. Split internal toothed saw disks are held by the holders which are openable. The holders are opened to facilitate the placing of the object inside the internal toothed saw disk. In order to introduce the object inside the internal toothed saw disk, one part of the annular internal toothed saw disk can incorporate a cut section so that the saw disk can be opened at this cut section.
