Know before you buy
Concave cutters remove a small amount of wood around the branch base, creating a slight indentation. This allows the tree's bark to heal over the wound more flush with the trunk, significantly reducing unsightly scarring.
No, these are designed specifically for delicate work like buds, new shoots, and small twigs. Attempting to cut thick or woody branches can damage the precision blades.
No, these cutters do not feature a spring. This design choice provides the user with more tactile control and precision when working on intricate bonsai details.
High carbon steel is prone to oxidation, so it is important to wipe the blades clean after every use. Periodically applying a light coat of camellia oil will help protect the metal and keep the cutting action smooth.
Yes, the design is fully ambidextrous, allowing for comfortable use regardless of your dominant hand.
