Yamashin has been producing honest, hard-working kitchen knives in Tosa, Japan for generations, and this White #1 Gyuto is a compelling introduction to what Japanese carbon steel can do. Tosa is one of Japan most productive knife-making regions, known for turning out blades that prioritize real-world performance over flash. Shirogami — meaning white paper steel — is among the purest carbon steels available, prized by sharpening enthusiasts for how easily it takes a razor edge and how well it holds it through heavy use.
The gyuto is Japan answer to the Western chef knife — a versatile, all-purpose blade that handles vegetables, proteins, and fish with equal confidence. At 210mm this one is a practical everyday length, long enough for most kitchen tasks without feeling unwieldy. The hammer-forged Shirogami #1 core is clad in soft iron that develops a rich patina over time, and the grind is particularly impressive for the price, with a behind-the-edge thinness that translates directly into effortless cutting performance. The walnut octagonal handle with black pakka wood ferrule rounds out a knife that looks and feels far more expensive than it is.
Customers with serious knife knowledge reserve special praise for this gyuto. A professional knife sharpener with years of experience calls it a standout edge-taker, reporting exceptional sharpness scores after time on the stones and noting it remains a daily go-to after two years of regular use. Others are impressed right out of the box, with the Shirogami steel living up to its reputation from the very first cuts.
Carbon steel care is straightforward. Wipe the blade clean during use and dry it immediately after washing. Avoid leaving water or acidic foods on the blade for any length of time. The soft iron cladding will develop a natural patina with use, which adds character and provides a measure of protection. Each knife is made by hand so measurements may vary.

As a professional knife sharpener and wannabe chef, I can’t sing the praises of this knife. Yep, it’s hefty and rustic, but of all the knives I have, nothing takes an edge like this. In use in our kitchen for two years now and it’s still my go to. After a spin on my Tormek T-8 and stropping on a roo hide, I managed a Bess score of 80. Comfortable, stiff, and non stick, all of my customers Rave about this blade. Thanks Mark for offering this superb blade. The Rev’s Edge

This is your workhorse type of knife, use for it a week in professional kitchen and I quite like it. The handle is nice for this price range, but it does have little gap between the blade and handle. I recommend putting some beeswax on it to prevent water getting into the handle. Also the knife come somewhat dull out of the box, but it’s super easy to sharpen. So I recommend paying for the sharpening service here, if you don’t know how to sharpen a knife. Once the knife is sharp it’s a joy to use!
