Scissors are the most commonly used bonsai tool and are the most crucial tool in the bonsai artists toolbox.
For the price, these black carbon steel 19cm scissors made in China cannot be beaten. You will be able to use them to cut twigs and even thin branches. Anything thicker and you should consider purchasing the Bonsai Branch Cutter.
The differences between scissors designed and made specifically for bonsai and normal scissors are many.
Bonsai scissors have a completely different shaped handle which makes a lot of cutting comfortable.
The blades are shaped differently and made considerably thicker to enable thicker cuts than a normal scissors can manage.
The tips of the blades also slightly overlap to enable clean cuts, which in turn enables faster healing.
