Bonsai Air-layering Tool by Koyo
Air-layering can be an amazing shortcut to quality bonsai. It takes a little practice, but it's not difficult, and once you get the hang of it, you'll be happy you did.
This unique tool has two settings, one for thin branches and one for thicker branches, but you can adjust it easily to any size up to almost 2" (5cm). The overall length of the tool is 6 & 5/8" (approx 17cm). Made in Japan by Koyo tools.
We originally thought this tool was designed for stripping bark to create jin (dead branches). Turns out it's for air-layering. However, we've tried it for bark stripping and it works!
