4. The KUSARIGAMA… the chain and sickle blade combo well known to martial art movie-goers. Another unique weapon classic with high potential offensive/defensive capabilities. Many women of the EDO period for example recognised this and became proficient in its use. It’s relatively light-weight construction and flowing CHAIN movement possibly enhanced/understood by female innate rhythm kept training levels high. The infamous MIYAMOTO MUSASHI NITO KEN ( double/twin SWORD techniques ) were even adapted by such as NITO SHINKAGE RYU to accomodate twin sickle usage. Needless to say the training was long and arduous.( Refer to intel #3+4 for DIY KUSARIGAMA + other   training weapon manufacture ideas ). A uniquely effective weaponry combo. Though… during training you may well find yourself wrapped in chain… Shiro did. photocredit/thanks:mlppolska
