Welcome to the Oshigata.nl website.

Oshigata are accurate drawings done to reproduce the smith's signature engraved on the nakago (the tang) if it is present, the Hamon (temper line), and other fine and subtle characteristics on the surface of the sword. An accurately drawn Oshigata helps the classification of a sword to a smith or school, it also is the unique "fingerprint" of each sword, a snapshot taken of its appearance at this moment. With a carefully done oshigata drawing a lot more detail can be seen in the sword than is possible with a photograph.

On this page is a selection of oshigata examples to show styles of different hamon treatment, and full-size oshigata examples of swords.
