Why is it important to recognize authenticity?
Buying an original Japanese knife is an investment in quality and durability. Imitations not only lack sharpness and durability, but can also be dangerous and impractical in the kitchen. Knowing how to identify an authentic knife will help you avoid fraud and enjoy a tool that can last a lifetime.
1. Steel: The key to authenticity
The type of steel is the first indicator of quality. Authentic Japanese knives use high-end steels such as:
-
VG10: Stainless steel with excellent edge retention and strength.
-
Aogami (Blue Steel) and Shirogami (White Steel): Carbon steels, famous for their cutting ability and easy sharpening.
-
SG2 (Super Gold 2): Powdered steel, ideal for those seeking maximum performance.
Advice:
If the knife only says "high-quality stainless steel" or doesn't specify the type, be wary. Imitations often hide the true material.

2. The construction of the blade: Tradition and technology
Traditional Japanese knives are made using advanced techniques:
-
San Mai: Three layers of steel; a hard core protected by two softer layers.
-
Honyaki: Forged from a single piece, reserved for master cutlers.
-
Damascus: Wavy patterns created by layers of steel, providing beauty and strength.
Attention:
Imitations often feature laser-engraved Damascus patterns, not the real thing. Authentic knives also have sharper cutting angles (12–15°) , allowing for more precise and clean cuts.

3. The handle: Ergonomics and authenticity
There are two types of mango:
-
Western Mango (Yo-handle): Ergonomics and balance, with metal reinforcements.
-
Japanese handle (Wa-handle): Lightweight, made of fine woods such as ebony or walnut, without metal reinforcements.
Advice:
Copies often use low-quality plastic or wood, with sloppy finishes.

4. Origin and brand: The guarantee of quality
An authentic Japanese knife should clearly indicate its origin. Look for:
-
Famous regions: Seki, Sakai, Echizen.
-
Kanji inscriptions: Name of the artisan or manufacturer.
-
Recognized brands: Sakai Takayuki, Masamoto, Shun, Misono, Kanetsugu.
Advice:
If there is no information about the origin or manufacturer, it is probably a fake.

5. Price: A key indicator
Authentic Japanese knives aren't cheap. Prices typically start at €80-100 and can reach several hundred euros, depending on the material and workmanship.
Attention:
A “Japanese” knife for less than €50 is almost certainly a copy.
