Start with your most frequent use. For a diet that is primarily plant-based, the Nakiri is designed for that purpose; for everyday meat, fish, and vegetables, the Santoku or Gyuto are better suited. As for the steel, a stainless steel such as VG-10 or Ginsan makes maintenance easier. A 16 to 18 cm blade is suitable for most home kitchens. Finally, a single well-maintained knife is more useful than a neglected collection.
Best Japanese knives
The essential blade shapes: Gyuto, Santoku, Nakiri and Bunka
Four blade shapes cover most culinary tasks. The Gyuto knives, Santoku knives and Nakiri knives from Stay Sharp clearly illustrate these differences in profile.
Wa handle or Western handle: what impact on the grip
The wa handle, traditional in Japan, is light, with an octagonal or D-shaped cross-section, often made of magnolia. It shifts the balance towards the blade and lends itself to a pinch grip, with the thumb and index finger placed on the heel. The Western handle, symmetrical and heavier, often made of pakkawood, brings the balance closer to the hand. A cook accustomed to European knives may start with the latter, then discover the wa.
Care and sharpening: the non-negotiable rules
Three rules preserve a Japanese knife. Wash it by hand, as the dishwasher dulls the edge and attacks the steel, especially Aogami and Shirogami. Dry it immediately after use to prevent oxidation. Sharpen it on a water stone, using 1000 grit to restore the edge, then 3000 to 6000 grit to refine it. This final step can also be entrusted to the sharpening service of Stay Sharp.
Blade finishes: Kurouchi, Tsuchime, Nashiji and Damascus
The finish changes the appearance of the blade and, sometimes, its cutting performance. Kurouchi preserves the black layer from the forge, for a raw look. Tsuchime features hammer marks that limit food adhesion. Nashiji, or "pear skin," offers a satin and textured surface. Damascus, finally, is a pattern obtained by layering or etching: it is not a steel, hence the importance of knowing the core steel.
Frequently Asked Questions
How to choose your first Japanese knife?
What is the difference between a handcrafted Japanese knife and a mass-produced knife?
An artisanal knife is forged by hand by a blacksmith, often named, in a production region identified as Sakai, Seki, or Tsubame-Sanjo. This manual work makes it possible to adjust the geometry of the blade, its thickness, and the heat treatment of the steel. A mass-produced knife follows an industrial process: its quality is consistent, but without these variations intended by the artisan. Stay Sharp blades come from Japanese artisans whose origin is documented.
Can you gradually put together a set of Japanese knives?
Yes, and it's often more sensible than buying a complete block right away. You start with an all-purpose knife, Santoku or Gyuto, then add a Petty for precision tasks. The Nakiri or Kiritsuke find their place when a specific use recurs regularly. At Stay Sharp, each size is purchased separately, without the obligation to take a set, allowing you to build your kit at the pace of your actual needs.
What is the difference between VG-10 steel and Aogami steel?
VG-10 is a stainless steel that contains cobalt and vanadium, among other elements. It is highly resistant to corrosion and is suitable for everyday use without strict maintenance. Aogami, available in #1 or #2, is a carbon steel: it can be sharpened to a very fine edge, but it oxidizes when exposed to moisture and develops a patina over time. Both are available in Santoku, Gyuto, and Nakiri styles from Stay Sharp.
Should you sharpen your Japanese knives yourself or use a professional sharpening service?
risk overheating the steel and rounding the bevel. Learning to sharpen takes a few hours of practice, which quickly pays off over the life of a knife. For those who prefer to delegate, Stay Sharp's sharpening service uses stones and accepts mail-in orders from anywhere in Canada.
