Thank you for viewing. This is a work by Master Noboru Nishine, famous for the Fukuro Nagasa and Matagi Nagasa. Created by the same person. 4.5 sun (unit of length, approximately 13.6 cm) I used it for camping, and the sharpness is excellent because it is forged. I think the sheath made of Akita cedar is also a wonderful item. Handmade forged product. Everything in the photos is included.
