B016 立鼓(リュウゴ) Ryuugo(Drum)
日本刀の柄の形の一種で柄の刃方、棟方双方にカーブ(内反り)がついています。
刃方がまっすぐなものを刃方一文字、刃方も外反りになっているものを諸反り
(太刀に多い)、反りが無いものを棒柄といったりします。
Ryuugo is a one of Tsuka(hilt) styles. It has a innner curve on its both side.
If edge side is straight,it's called "Hagataichimonji(=edge side straight).
If both side is outer curve,it's called "Morozori(=Both curve).
If no curve,it's called "Bozuka"(=stick).
