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.

  • Unlike German made knives, Japanese knife blades are ground to thin cutting edge for sharper cutting and easier re-sharpening. Please protect the edge from hitting hard materials to avoid chipping or cracking.

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

A fine knife at a reasonable price

Overall - delightful. I purchased the 210mm Wa Gyuto some time back (2 years? 3 years?). In any event, it's a well-balanced blade that is readily sharpened and retains its edge better than all but a couple of knives I own (and I own several). I use it primarily for vegetable prep. While it sells as a 210, mine is closer to 220, which I like. It absolute terms, it's a fine knife. For the price, I don't think it can be beat.

Now this is my main knife for work

This is the third knife that I buy on this site. This time I was looking for a light knife. I am a professional cook and a good knife is very important for me. I've always used Santoku before. Decided to try Gyuto. The knife is very convenient to work. Thanks!

I have this knife for 3 years, sharpen every 3 months. I cook every day. However, recently sharpened it a year ago - today I just sharpened because I started to annoy the lack of focus when cutting tomato.
