Care Instruction

Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
Wash with neutral detergent after use, and wipe dry;
Please don't wash knife with dishwasher, it will damage the wood handle;
Be careful not to leave the knife close to a heat source for a long time;
It is a lot more dangerous to cut with a blunt knife than a sharp knife!
It is best to sharpen a Japanese knife regularly on a waterstone.

Tsunehisa

Tsunehisa isn’t tied to one workshop – it’s a celebration of all Japan’s great knife regions. Think Sakai’s laser-precision grinds, Tosa’s mastery of steels like Ginsan, and the distinct traditions of other forging hubs, all united under one brand. By pooling this regional expertise, Tsunehisa delivers exceptional handmade quality at surprisingly accessible prices.

Each knife reflects thoughtful design and rigorous quality control by the Ironclad group (led by Shibata Takayuki). You get authentic techniques – hand-forging, perfect heat treats – paired with modern functionality and Japan's finest steels. Clean aesthetics ensure they look as good as they perform.

Tsunehisa believes a great knife should be a lifelong companion. That’s why they combine serious performance with dedicated after-sales care, including sharpening support. It’s genuine Japanese craftsmanship, distilled for cooks who value both heritage and smart value.

Profile: Gyuto

Chefs Knife
A Japanese chef's knife is known as a gyuto (牛刀ぎゅうとう） gyūtō?), literally meaning 'beef knife'. Its blade resembles a flatter version of a French chef's knife. Japanese cutlery is known for sharpness due to its acute blade geometry, and the hardness of the steel used, sometimes exceeding 60 HRC on the Rockwell Scale A typical western chef's knife may be sharpened to an edge angle of 20-22°, while a Japanese gyuto generally has a sharper edge angle of 15-18° (or even lower), which requires a harder, more brittle grade of steel. In recent years Japanese gyuto have gained in popularity with western chefs.

A modern chef's knife is a multi-purpose knife designed to perform well at many differing kitchen tasks, rather than excelling at any one in particular. It can be used for mincing, slicing, and chopping vegetables, slicing meat, and disjointing large cuts.

Steel: SLD
Hitachi SLD steel is a tool steel designed originally for die and machining tools. Its composition is practically identical to the D2 tool steel - a classic steel that have withstands the test of time since the WW2. The high level of Chromium content in it have made this steel almost stainless, and the decent amount of Molybdenum and Vanadium forms hard carbide, given this steel a pretty good edge retention. The toughness may be average of its kind, but it shouldn't be a big concern under the condition of normal kitchen use. SLD steel would be a good choice for those who are looking for a steel that can develop a keen edge, but not as attention demanding as a classic carbon steel.
Manufacturer:
- Hitachi Special Steel, Japan
Nature: Stainless

Construction: Sanmai - Stainless Clad

Sanmai(Three-Piece) is a common construction for double bevel knives where two pieces of softer cladding steel are forgewelded to each side of a harder core steel. The harder but more brittle core steel will form the hard cutting edge after heat treating, and the softer cladding will support the core to increase the overall strength of the blade.
The soft cladding enables the thinning process to be a lot easier than a honyaki or monosteel construction. And in the case where the cladding steel are stainless in nature, it can offer protection for the carbon or semi-stainless cores against rusting and discoluoring.

Finish: Nashiji

The "nashiji finish" on Japanese kitchen knives refers to a unique, textured surface finish that resembles the skin of an Asian pear, which is known as "nashi" in Japanese. This finish is achieved through a specific hammering and polishing technique, giving the knife blade a distinct, matte appearance with a slightly uneven, tactile surface. Beyond its aesthetic appeal, the nashiji finish also provides practical benefits. It helps to reduce food sticking to the blade by creating tiny air pockets between the food and the steel. This finish is commonly found on traditional Japanese knives, such as santokus and nakiris, and is highly valued for both its functional and visual characteristics, enhancing the overall culinary experience.

Handle Specs
Profile: Octagonal WA
Material:
- Kashi - Japanese Oak
This handle utilizes premium Kashi (Japanese White Oak) as its foundation. In this variation, one half of the handle undergoes a controlled charring process.
This technique transforms the wood's appearance: the burnt section develops a deep, rich hue and pronounced texture, creating a striking visual contrast against the untouched, warm-toned Kashi on the other half. The charring process can also accentuate the wood's inherent medullary ray figuring, adding further depth and complexity.
Despite the dramatic visual effect, the core stability and durability characteristic of Kashi remain. The charred surface provides a unique tactile quality while maintaining the material's inherent resilience. This treatment results in a handle offering both bold visual distinction and the reliable performance expected of Japanese white oak.
