Tojiro Shippu Bread Knife

The bread knife, as its name suggests, is specialized for slicing through bread without crushing it. Developed in Germany and the United States in the late 19th century, its serrated edge can saw through the crust without exerting pressure on the bread, giving a clean, non-destructive cut. The serrated edge also makes it useful for other foods with hard exteriors and soft cores, as well as anything fibrous.

Tojiro Shippu and Shippu Black blades are forged from 63-layer (all larger knives) or 37-layer (paring, peeling, and petty knives) Damascus steel, which is made by repeatedly folding and forge welding two stainless steels with different carbon contents. The resulting material bears the elegant, wavelike pattern produced by its many fine layers—a testament to its strength, flexibility, and durability. This Damascus envelops a core of harder VG-10 cobalt alloy steel, a high-carbon stainless steel developed in Japan. Hardened to HRC 62, it accommodates a long-lasting, razor-sharp edge.

Damascus steel was first developed in India over 2,000 years ago and quickly established a reputation not only for its beauty, but also as one of the greatest metallurgical innovations in history. Swords forged in Persia and sold in the Syrian city of Damascus inspired legends of their ability to slice through a gun barrel or part a hair falling across the blade. Although the ancient technique was lost to history around 1900, modern metallurgists have succeeded in reproducing the effect with state-of-the-art alloys to bring performance to the next level.

The handle is crafted from lightweight chestnut wood, which provides a secure grip without upsetting the knife’s balance. The wood is fire-blackened, enhancing its durability and water resistance, and secured with a ferrule (collar) of polypropylene resin. Its D-shaped shinogi profile maximizes comfort and ease of control.

Wash your knife by hand with warm water, soap, and a soft sponge or dish towel. Avoid prolonged exposure to heat or moisture. Remember—there's no such thing as a dishwasher-safe knife!

To prevent edge chips, avoid impacts with hard surfaces. Don't chop bones, shells, or frozen food, and cut only on a wood or bamboo cutting board. Don't leave your knife where the edge might come in contact with something hard, such as in a sink or a drawer with other knives.

Store your knife so that the edge is protected from abrasion and impact. We recommend a magnetic stand, but you can also use a knife block with horizontal slots. If you must keep it in a drawer, use an edge protector. See our storage options here.

Serrated knives stay sharp longer than most other types and are usually not feasible to sharpen at home, but with practice, it can be done with a round file, a small diamond sharpening rod, or the edge of a coarse whetstone.
