Abstract: Hand-held and hand-operated cutting tool particularly well suited for cleanly and quickly cutting plastic pipe or tubing, rubber hose, or the like. The tool has a blade rotatable in increments or steps from a retracted position in which it is enclosed within a housing to a cutoff position in which it cooperates with a stationary anvil so as to sever the article to be cut. A ratchet drive interconnects a movable handle and the blade so as to incrementally drive the blade toward its cutoff position upon manipulation of the handle. A pawl prevents opening of the blade caused by the springiness of the article being cut upon being engaged by the blade. Upon severing of the article, the blade may be readily returned to its retracted position by, for example, releasing a thumb operated locking pawl.

Abstract: A cage slot grinding machine having a work head whose work spindle is rotationally indexable by an index device and first and second wheel supports which respectively carry first and second grinding wheels for grinding, two at a time, cage slots of a cage member on the work spindle.
