Apologies for my candour, but I don’t have a great deal of time free to post reams of wisdom to rather foolhardy questions. There’s a lot of Green Belt Syndrome in the martial arts, and I tire easily. Perhaps I shouldn’t have replied at all. Being not an absolute beginner with tachi or daisho, does that give me any real understanding of other sword principles? Can I just pick up an English backsword or an Indian Talwar and use it well? Hell no. Now imagine attempting to wield a kusarigama without experience, as you wish to do. You will be more of a liability to yourself than to your enemies. I have used a kusarigama and they are INSANE (but a lot of fun). If you a) haven’t actually used weapons in combat or b) follow a lineage that has indeed done that, you are just kidding yourself if you think you are learning a weapon art. Being a monster with nunchaku doesn’t give you any insight into surujin. What is your experience to date with weapons? Please try and be honest about your level of understanding - and perhaps tell us the line of study you follow? I think my opinion has been explained perfectly well? Good luck with the seminars.
