(under subclass 445) Implement wherein the penpoint terminates in only two elements which are separated by a relatively narrow slit or interspace to provide a capillary passage for material, and which have closely adjacent work-engaging surfaces.
(1) Note. Ink retained in the space between confronting surfaces of a broad face tool (e.g., ruling pen) is
considered to be material supply, and an implement having such a tool is considered to be an implement with material supply for Class 401. A patent for such an implement will be found in subclass 221 of that class (401) and a patent for such an implement further including means to adjust the gap between the tool elements will be found in subclasses 233 and 256 of that class.

446, for a bifurcate penpoint wherein novelty is in the composition or kind of material thereof.
SEE OR SEARCH CLASS
401, Coating Implements With Material Supply, 221+, for an implement of that class including a bifurcate penpoint; see, particularly, principal subclass 221 wherein the penpoint is formed with an ink-retaining element (e.g., infolded wings) and indented subclasses 252+ wherein the ink retainer is an attachment feeding directly to the penpoint.
