Sha Ra Ku Mono Tomato Knife, 130 mm (5.1")

Tomatoes are among the most notoriously challenging foods to cut, thanks to their thin, tough skin and soft, messy interior. The Sha Ra Ku Mono tomato knife's ultrafine serrations (35 per inch) allow it to saw cleanly through the skin without applying pressure, but it doesn't stop there—this knife is good for any hard or fibrous foods that are challenging with a plain-edged knife.

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.

Finely serrated knives stay sharp longer than most other types but are usually not feasible to sharpen at home. Professional sharpening services like Seattle Cutlery's can buff the blade to extend its life, and when the serrations are too worn down, it can be sharpened into a plain edge.
