Bonsai Branch Bender by Roshi Tools - 3.5"
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. 3.5" (9cm).
