The bamboo I have always dealt with is from china, and it is from the Tonkin River Valley, and as you can see, it is quite different from the river cane photo that DC posted. (thanks DC) I am a professional arrow maker and all I do is Bamboo. Apparently, what I have been using is a different thing entirely. Happy to answer any questions about bamboo, but I can't speak to river cane. Best to all, and I'm looking forward to some great discussions. If you want to see what the Tonkin River Bamboo (some call it the Tonkin River Reed) here is a photo. You can see why I was surprised by the look of river cane such as DC uses. Best to all, and just so you know...I'm new to this.
