SUWADA Bonsai Knob Cutter
SUWADA's original knob cutter is designed to refine the area left after a branch is removed. Its rounded cutting head creates a controlled concave gouge rather than leaving a protruding surface.
This shape gives bark a less raised surface to grow over as the tree develops. Use a knob cutter for refining branch-removal cuts rather than as the primary tool for taking off a whole branch at the trunk.

Let customers speak for us
Incredible product and craftsmanship. The clippers along with the case have a high quality feel and your nails feel smooth after each cut
As someone who has finally quit to bite and eat my nails, and who also happens to have OCD, this object is a part of the nest purchases I have made.
Perfect instrument worth every penny.
Beautiful teapot from Kogu. I saw this one while I was in Japan and fell in love with the design. The material is beautiful and the size is perfect. Also the packaging was lovely and shipping was very fast.
To be honest, I bought the case solely because it protects the nippers and fits them perfectly; I didn't bother looking for a different $5 option that would offer the same fit. Unlike the nippers—which are simply flawless—the case is vastly overpriced; the cost of three cases equals the price of one pair of nippers. Yet, the nippers represent sheer perfection and embody a huge amount of time and effort, whereas the case is just a piece of leather stitched together.
I spent a long time deciding whether to buy size S or L, so I ended up buying both. I had never used cutters like these before, but when I tried them out, I found the blades to be incredibly sharp and precisely aligned. The leverage mechanism works perfectly—there is absolutely no play, and everything fits together tightly. Having worked as a fitter for ten years, I appreciate tools that perform with precision and flawlessness; I even examined them under a magnifying glass and couldn't find a single defect—it is truly amazing that these cutters have been perfected to such a degree.
I am really happy with the Suwada Round Nail Clipper. The quality feels exceptional from the moment you hold it, and the precision is truly impressive. It cuts very cleanly and smoothly, which makes nail care feel much easier and more controlled.
What I like most is how accurate it is, especially around the edges of the nails. It gives a neat result without needing much effort. The design also feels solid, elegant and made to last.
Overall, I am very pleased with this nail clipper. It is definitely a premium product, but the precision, comfort and quality make it worth it for me.
Perfect craftsmanship. +They’re so sharp that they cut very smoothly (no snapping) and accurately. That’s the quality I love. The straight & pointy edge on this model is definitely the best for big toes nails. Consequently, the rest is a breeze.
The product performs with precision and ease. It’s saves time and efforts, but midst important, done properly it helps to not hurt you skin.
Deep frying chicken or shrimps with oil needs a lot. It makes sense to re-use it again the oil for next time. Hence we find this a very utilitarian item of importance, which helps in re-using the oil. It also comes with a filter. The filter keeps the over-fried fritters out of the oil.
