(under subclass 254) Shears in which one blade has a slot into which the other blade moves during the cutting operation. These shears usually cut out a narrow strip of the material.
(1) Note. Where one blade enters a slot in the other blade and wedges the material against the side of the slot for the purpose of gripping it, see this class, subclasses 134+.
(2) Note. Where the slotted member merely constitutes a sheath for the cutting blade, see this class, subclass 155.
