  Kurimata style Yanone

bulletSigned - Sashu Masamori  (薩州正盛) ca. 1724

Yanone of this and similar shapes are known as rope cutters, however the actual function of these arrow heads is arguable.

Polishing a Japanese Yanone (Arrowhead)

In early 2001 this kurimata style Yanone was sent to Japan with sword  polisher Naoji Kurita, for polish and shirasaya. As one might expect this shape is difficult to polish, requiring many small stones. This yanone took three days to polish and has several areas that made this more difficult. Mr. Karita is well known for his Oshigata and he provides an original Oshigata for each polished blade.

The blade is signed on the left side of each face, like many kurimata style arrowheads. One side is signed with the province: Sasshu (Satsuma), and the other is the smith: Masamori. He was working in the province of Satsuma (Today's Kagoshima) during the Kyoho Era (1716-1735). The links below show close up views of the blade and the Oshigata, The blade was scanned and the hamon is hard to see. In the near future I will add some digital photos so that the hamon can be seen.
