(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. SEE OR SEARCH CLASS
