We are currently working on a bamboo wading staff. It is not split-bamboo but is instead made from a complete bamboo culm. And rather than Tonkin bamboo, we are making these of Calcutta bamboo from India. You'll have to choice of a rubber-like elastomer cork or black grip. The leash is 22" long of 3/16" shock cord and can be attached to your person with a small aluminum carabiner. The tip has a stainless steel insert or you can use the included rubber tip. They'll come in two lengths, 48" and 54".
We should have these available in the next few weeks. Let us know what you think!
