I’ve noticed on some haidate a cord that twists across horizontally above the plates. As seen at the bottom of the attached photo. It seems to me it might be there to pull the top horizontal chikara gawa strip in, above a bump, but that’s only a guess. I understand the reasons for all the components of the different types of Haidate. But this “string” has got me confused. If anyone can explain for me why it’s there, and what it’s function is, I’d be very grateful 😁👍🏼
