Tojiro Zen Petty Knife
Tojiro Zen Petty Knife
FD-562
Tojiro’s Zen series is forged in Tsubame, Japan, and features the same design, chestnut handle, and fine craftsmanship as the premium Shippu series, but utilizes three-layer san mai construction for strength instead of Damascus steel. Like the rest of Tojiro’s premium traditional lines, Zen is imported exclusively by Seattle Cutlery.
Function
Function
The petty or utility knife is a small, multipurpose blade that offers the versatility of a chef’s knife in a smaller package. Developed in Japan in the late 19th century with influence from European patterns, the petty knife's gently curved blade is useful for paring fruits and vegetables, slicing meat, chopping small produce, carving, and other tasks.
Blade
Blade
The blade is made using the centuries-old san mai (“three-layer”) construction technique, in which a hardened steel core is forge welded to a jacket of softer, more flexible steel for strength. Nakiyo San Mai blades are forged with a core of VG-10 cobalt alloy steel, a high-carbon stainless steel developed in Japan. Hardened to a Rockwell hardness of 60, it accommodates a long-lasting, razor-sharp edge. The core is clad in 13 chrome stainless steel, which strengthens the blade and guards against corrosion.
Handle
Handle
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.

Care & Maintenance
Care & Maintenance
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.
Sharpening
Sharpening
Sharpen on a whetstone at an angle of 15° per side and finish at a grit of at least 1000, but preferably 3000 or higher. Pull-through and electric sharpeners should be avoided for Japanese knives.
Alternatively, you can have your knives sharpened professionally. Seattle Cutlery offers a state-of-the-art, mail-in sharpening service for our own customers, but other services may be available to you locally.
Honing steels are not necessary to maintain Japanese knives. You can optionally touch up the edge with a high-grit sharpening stone or a ceramic sharpening rod.
