This is a large bifurcated (two points) yanone done in the karimata shape. Although this type of yanone is often referred to as a “Rope Cutter” in actuality, the primary function was as a flesh cutter used in battle and/or for large game animals.
This karimata shaped yanone is signed on the blade on both sides, with the signature being feint and difficult to read. It is very graceful and shows no damage. The hamon is visible in places and would look great if polished. The hamon is suguha. The shoulder is a hex shape.
The nakago is 7-1/4 inches (18.4cm) long, the blade is 2-1/2 inches (6.4cm) long and 2 inches (5.1cm) wide. Estimated to be from the middle Edo era.
