(under subclass 173) Implements in which at least one of the cooperating blades is rotary.
(1) Note. Tailors' cloth cutting machines are here, as well as in subclasses 273+.
(2) Note. The patents in this group are to be distinguished from the shear subclasses, since here the blade edges do not
move past each other in the cutting operation, although some are called shears.
(3) Note. Many of the patents here are base supported and in that respect are like those in subclasses 273+, and search for the base feature should be continued there.
(4) Note. For rotary blades, per se, see this class, subclass 347, and see the notes thereunder for other rotary blade cutting tools.
