(under subclass 64) Apparatus comprising: (a) a cutting device which is capable of movement in a path instantaneously

under the control of the operative during cutting, including a cutting device suspended or supported near the workpiece; (b) a cutting device which as an entirety is disclosed as deriving from the work a substantial amount of its support against gravity during cutting; or (c) a cutting device which is intended to move across the workpiece in a direction dictated by conditions of the workpiece.
