These bonsai root cutters are very versatile tools. First it should be pointed at that they are designed to be strong and are rather robust tools so can safely be used for making demanding cuts.
Primarily these root cutters were designed for removing roots when repotting. As time passes, the roots of your bonsai thicken in the pot. These roots are not desirable as they favour storage of foodstuffs rather than collecting it. The kind of root we need to encourage are the fine feeder roots. So we need to remove these thick roots every time we repot. This process also promotes better looking surface roots.
The other uses of these root cutters include shaping of large cuts. You can use the tool to nibble away at the excess wood which needs to be removed. It is better to use a tool like this than to use a branch cutter, and risk breaking it.
These high quality root cutters are made in Japan by craftsmen who have trained for a minimum of 10 years to achieve the skills required to product tools of such high precision. As with all our Kaneshin tools, these branch cutters are handmade and each tool is boxed and accompanied by a certificate of authenticity.
Tip: To cut safely and without potentially damaging the tool, the branch thickness to be cut cannot be more than 1/2 to 1/3rd the length of the blade.
