Bonsai Branch Bender by Koyo - 4"
Got a pesky little curve in a formal upright that's too tough for bonsai wire? Or a stiff old section that needs a little movement? Try a branch bender.
After you put it on, tighten the jack screw a little bit every few days until you get the results you're looking for. Then leave it on long enough for the wood to set in its new position .
Made from steel with a brass jack screw. The hooks and jacks are coated with vinyl to protect trunks and branches, though some people do use additional padding.
4" (10cm). Made in Japan by Koyo Quality Tools.
