Hello!
I‘ve been doing tkd for just over a decade and have just thought to look into it. Literally the only thing I can spell is Koryo, which I need to fix. For context I’m not korean at all, I’m American, but my school is very traditional style tkd and I do know quite a bit about the founding and the reasons behind it.
We use this cane basically instead of our hands and you can incorporate it into all of your forms. I think it’s bamboo(?) and it’s around the size of a yard stick and you hold it in thirds, I’m going to attach a picture. I received it after I first became a black belt.
I’ve been trying to find it online and it’s not coming up anywhere. The only thing I can find is a hapkido cane which I’ve never seen in my life though have found a good deal about through this side quest.
