This knife comes with 50/50 double bevel edge geometry for both right and left handed use.

For your information, Japanese Kitchen knives are generally designed for right hand use with a slightly thicker and rounded grinding on the right side blade and a less rounded (almost straight flat) grinding on the left side blade. However, both right and left hander can use the knives that have double bevel edge sharpened 50/50 without problems.  

We believe quality and performance of Japanese knives are best in the world and hope you enjoy fine craftsmanship and spirits from your new knife. With proper cares, every Japanese knife can be your special cooking partner for long time.

  • We recommend re-sharpening the knife using Japanese whetstones, when it gets dull.
