DEFINITION

Classification: 83/523

(under the class definition) Device including either a tool

or tool pair and means to apply a force to either or both tools to effect at least a part of a cutting stroke or cycle or means to constrain a tool for motion in a path defining a cutting stroke or cycle.

651+, for cutting tool claimed, per se, that is, without means to drive or constrain a tool to move in a cutting stroke.

144, Woodworking,

28.3+, for a pencil-sharpening machine (i.e., one including a cutter and a pointing-facilitating work holder or work guide) including means to drive or guide the cutter. 173, Tool Driving or Impacting, appropriate subclass for a means to drive or impact a tool or the like.
