Sha Ra Ku Mono Nakiri, 180 mm (7.1")

The nakiri bōchō (菜切り包丁), “knife for cutting greens,” is a traditional Japanese vegetable knife best used for up-and-down chopping. Unlike the santoku and gyuto (chef’s knife), which have narrow tips intended for cutting meat, the nakiri has a square tip and broad blade that maximize chopping power along the full length of the knife. The straighter edge ensures full contact with the cutting board, helping to cut through tough vegetable skins that a rounded edge can miss, while the rounded corner facilitates rock-chopping. Like other Japanese knives, the nakiri has a thinner blade and more acute edge than European knives, so it can effortlessly make straight cuts and doesn’t break stiff vegetable slices.

The Sha Ra Ku Mono nakiri is available in two sizes. The 180 mm (7.1") length is more versatile, but the 160 mm (6.3") length gives better control for smaller items.

Sha Ra Ku Mono blades are forged from molybdenum-vanadium alloy stainless steel, which finely balances edge retention, toughness, and corrosion resistance. This alloy is softer than the VG-10 steel used in other Tojiro knives but harder than European knife steels and is comparatively easy to sharpen.

The handle is made from hollow 18/8 stainless steel, crafted with the blade as a single piece. Much like a traditional wooden wa handle, its light weight keeps the knife's balance farther forward than on European knives. The ergonomic shape allows it to be gripped either by the handle or with a more versatile pinch grip.

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.

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.
