Tojiro Zen Black Paring Knife

The paring knife is a short knife intended for fruits and small vegetables. As the smallest knife commonly encountered in the kitchen, this knife is perfect for intricate tasks like paring and is generally considered to be a core component of the chef’s arsenal.

Function

As its name suggests, the paring knife is best suited for paring fruits and produce due to its short, agile blade. The knife’s narrow point also makes it useful for tasks such as deveining shrimp, coring fruits, and precisely removing spots. Tojiro’s Japanese paring knife is set apart from Western counterparts by the straight, angled blade, which also allows the knife to be used on a cutting board while maintaining clearance between the handle and cutting surface.

Form

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 steel for strength. Tojiro Zen and Zen Black 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.

Zen Black blades are additionally treated with a black oxide conversion finish, which anodizes a microscopic layer of metal on the surface to chemically stable magnetite (Fe₃O₄). Often used on medical implements, this treatment improves the steel’s resistance to saltwater and is popular on boats or in coastal areas.

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.
