DEFINITION
Classification: 30/
(1) This is the broad generic class for cutting implements including those for cutting by a sharp point, which are manipulable by hand so as to be movable in their entirety relative to the work during the cutting operation as distinguished from moving the work relative to the cutter. Such implements may be power operated and the motive power means may be built into the structure of the cutting implement.
(2) This class also includes some special machines which are not hand manipulable, as above defined, namely, special machines and fixed cutters in which the work moves relative to the machine or cutter, since these structures are too closely related to the hand cutters to separate; see necked receptacle seal cutters, can openers, carton openers, cigar tip cutters, cord cutters, and segmenters. (See Subclass References to the Current Class, below.)
(3) This class also includes hand manipulable scrapers having a sharpened scraping or cutting edge.
(4) This class also includes culinary and table forks and spoons due to their close relation to knives in use and manufacture.
(5) Many hand manipulable cutters under the above definition
have not been placed in this class. Their location is set forth in the notes appended to the definitions of this class and the subclasses thereunder.
(6) Many hand manipulable instruments having structure for cutting and in addition structure for performing other functions, such that the combination is restricted to some special art use, are not in this class but with the appropriate art class, as set forth in References to Other Classes, below.

7, Compound Tools,

132, Toilet,
75.6, and 76.4 for a manicuring abrader, file, or buffer. See (2) ABRADING MACHINE OR TOOL:
451, Abrading, for a tool which cuts by the abrasive action of a natural cutting media (e.g., the sharp edges of randomly positioned crystals) as distinguished from an "artificial" cutting edge such as is formed on a file, milling tool,
knife, shear, etc. Class 30 takes a blade holder designed to hold a specific blade relative to a stone or strop, generally. Class 451 takes a blade holder, generally; and takes a blade holder designed to hold a specific blade relative to a stone or strop only when including a "special feature" which renders the holder unsuitable for use with a general purpose knife. Examples of a "special feature" are: (1) Means for reversing a blade relative to a strop or abrading stone, (2) An opening or guide in a blade support or guide to determine the relationship of the blade to a strop or stone, (3) Means at or in front of the cutting edge to prevent improper contact between a blade edge and a strop or stone.
