Specifications

The Miyazaki kurouchi tanjirentetsu shirogami#1 gyuto 245mm is a Japanese chef's knife hand-forged in Nagasaki by Haruki Miyazaki. The blade has a Shirogami#1 carbon steel core clad in wrought iron (rentetsu). Shirogami#1 has one of the highest carbon contents among Japanese knife steels, known for taking a very fine edge and excellent edge holding. The etched finish brings out the wrought iron's distinctive wood-like grain. At 296g with a 248mm cutting edge, it's a hefty knife with an authoritative presence in hand. Fitted with an octagonal mono ebony handle.

Rentetsu (wrought iron)

Wrought iron was widely used in the 1800s for anchor chains, wagon wheels, and other applications. It is no longer commercially produced, so all wrought iron available today is reclaimed from century-old structures and artifacts. Its fibrous structure creates a distinctive streaky grain, unique to each blade. For this knife, the wrought iron we provided to Miyazaki-san is from the mid-1800s.

Note on Wrought Iron Characteristics

Wrought iron naturally contains slag inclusions. During the forging process, these inclusions may be dislodged, leaving small voids or pockets along the grain lines or on the spine. This is a natural characteristic of wrought iron, not a defect.

FAQ

Why is the blade length different from the displayed size? The size in the product title is a nominal reference used by knife makers. The actual blade can be slightly longer or shorter due to handcrafting and traditional sizing. Each product page lists the exact measured length.
