Know before you buy
While specifically engineered for root pruning during repotting, these cutters are also effective for trimming small to medium branches up to 10mm in diameter. They are designed for both live wood and root systems.
No, this model does not feature a spring. The design relies on the long handles to provide the necessary leverage for clean, controlled cuts, which is a common preference among bonsai professionals for greater tactile feedback.
Yes, because these blades are crafted from high-quality Yasuki-Hagane steel, they are susceptible to rust if left wet or dirty. We recommend wiping the blades clean and applying a light coat of camellia oil after each use to maintain their edge and prevent corrosion.
The 10.6-inch length provides excellent leverage, but the handle span may feel wide for those with very small hands. However, the ambidextrous design and non-slip grip ensure they remain stable and easy to handle regardless of your dominant hand.
To maintain the precision of the bypass mechanism, you should sharpen the blades periodically using a whetstone or a dedicated bonsai tool sharpening stone. Avoid cutting wire or overly hard materials, as this can chip the high-carbon steel edge.
