Class 030
CUTLERY
Class Definition:
(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.

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. Search particularly 419 for an abrading device

Devices for holding detachable cutting blades.
(1) Note. The holder may be claimed, per se, or in
combination with the blade.
(2) Note. The patents in this group are for holding a blade
without a guard for shaving purposes, for sharpening
purposes, and for use as a knife or scraper.
(3) Note. Connections between a blade having a tang and its
handle will be found in this class, subclass 341 et seq.,
except when there noted to be elsewhere.
(4) Note. For detachable blade razors having guarded
cutting edges, see this class, subclasses 51+.
(5) Note. Compare also this class, subclasses 2, 27, and
30+.
(6) Note. For sheath knives having detachable blades, see
this class, subclasses 156+.
(8) Note. Where a blade has a tang which enters a socket in
the handle with means to hold the tang in the socket, search
should be made in Class 279, Chucks or Sockets, subclass 9.1,
or the appropriate indented subclass. The mere naming of the
blade as a knife blade in the claims will not operate to keep
the patent out of Class 279.

Subclass:
401
This subclass is indented under subclass 400. Device having
means for: (a) detecting any of the following
characteristics: a state or property; or a change in a state
or property. The occurrence of a predetermined event in any
of the following: the container or its contents; the can
opener itself, or the environment of the can opener affecting
the operation thereof; and (b) initiating or terminating (as
a result of such detection) a force or impulse other than
that generated or transmitted by the detecting means; and (c)
regulating or modifying (as a direct result of such
initiation) the operation of the can opener.
(1) Note. This definition requires a patent to claim at
least 4 instrument abilities for original placement herein.
One of these must be a can opener. The other 3 are: (a) a
senser (e.g., trip lever, push button, photo cell system) to
detect a condition as stated in (a) of the definition; (b) an
activator (e.g., an element to make-break an electric
circuit, a clutch, a valve) to cause a release of energy more
than, or different from that accounted for by mere change of
condition (e.g., position or movement) of the senser while it
is functioning, and (c) a controller (e.g., a motor or
driver) to change or cause the operation of the can opener.
Therefore, a cam follower, (or senser) directly linked to the
controller, whereby follower movement directly effects
controller movement is not proper subject matter for this
subclass due to lack of an activator as defined above. On
the other hand, disclosure of a cam follower that makes and
breaks an electrical circuit that energizes a motor, may be
placed herein.
(2) Note. Patents claiming an on-off switch for activating
a motor circuit, and which is adapted to be voluntarily
manipulated by the operative, will be placed as originals
herein.
