Document Type and Number:
WIPO Patent Application WO/2016/006275
Kind Code:
A1
Abstract:
The present invention uses a material that is not conventionally used in fountain pen nibs in order to provide a fountain pen nib that is completely different from the prior art. This found pen nib comprises one of corundum, topaz, emerald, and garnet as a main material. It is also possible to replace the heart hole and the slit of the nib with a groove that is added to the rear surface of the nib. By using one of the abovementioned gems as the main material in a fountain pen nib, it is possible to achieve wear resistance and chemical resistance in the fountain pen nib while imparting a luxurious feel and originality to a fountain pen.
