One of the most essential and practical tools to have when you own a Bonsai tree is a knob cutter. This quality tool features a fully rounded cutting edge which will allow you to cut off the knobs on your bonsai tree, leaving a smoother, more flush wound on the trunk or branch. This process helps facilitate smooth callusing, which helps with the trees' healing process as well as giving a more visually pleasing result. Our steel knob cutter measures approximately 175mm in length and is sourced from China. These hard-wearing and durable tools can easily last many, many years, with minimal maintenance.
