Tojiro Nakiri Shirogami Kuro-uchi 165mm (6.5")
- Knife Care
Tojiro Nakiri Shirogami Kuro-uchi 165mm (6.5") is a traditional Japanese kitchen knife with a kuro-uchi blade finish and a hand-forged kanji. Nakiri blade shape is a traditional Japanese knife shape, designed for the task of cutting vegetables. A knife that will be appreciated in the hands of a prep cook with mountains of veggies to prepare every day! Recently, many nakiris find their way into home kitchens – it's a perfect knife for vegetarians and veggie lovers.
The knife is forged from Shirogami steel (white steel) and features a rustic kuro-uchi finish with a hand-forged kanji. The blade has a hardness of 61-62 HRC and, due to its low chromium content, acquires a patina over the course of use.
Nakiri is a traditional Japanese knife with a square, thin blade and a deep, flat belly. Since the entire flat edge of the knife touches the cutting board at once, in one clean, vertical movement, there is no need for a horizontal pull or push. This also means that you won’t be turning the vegetable into an “accordion” of pieces still clinging together by a thread. Due to its characteristics, it’s mostly intended to be used for chopping veg, but you can still use it as a good all-rounder in the kitchen.
The knife’s core is Shirogami #2 steel, surrounded by two layers of stainless steel that also hugs the spine of the blade. The knife is hardened to 62-63 HRC.
🚩 The steel will gradually acquire a patina which only endows this knife with more charm. Do not wash this knife in a dishwasher, but rather wash it by hand and wipe it with a dry cloth. The advantage of having a blade made of high carbon steel is the fine sharpness, ease of sharpening, and long edge retention. We recommend the occasional coat of knife maintenance oil to protect the blade from external influences.
The excellent Shirogami steel is clad into 2 layers of softer steel. The outer two layers of softer stainless steel form a "shinogi" line along the entire edge of the blade. Shinogi line represents the border between the harder, inner steel and the outer two layers of softer steel. The lamination is called san-mai cladding.
It has a double bevel (symmetrical) blade.
The knife was left an unprocessed black patina on top of the blade, called kuro-uchi, which gives it a raw, unfinished look.
The blade is attached to a traditional Japanese D-shaped handle, made of magnolia wood with a plastic ferrule.

☝️ THIS KNIFE MAY DEVELOP PATINA
Knives made of carbon steels can, due to their low chromium (Cr) content, discolor and develop patina. The knife is the most sensitive when it is still new and a patina had not developed yet, but later, patina will protect the blade. These types of knives require a touch more care:
✔ Wipe it regularly with a clean and dry cloth (you can also do this during use).
✔ After use, rinse it with lukewarm water and wipe it dry.
✔ Coat it regularly with knife maintenance oil or plain refined sunflower oil.
✔ Store the knife by wrapping it in paper which will absorb moisture and protect the blade.
A patina is a thin layer that forms on the surface of oxidized steel and protects it from further oxidation. The patina should not be confused with rust. Patina protects the blade, while rust causes corrosion and deterioration of material, so it should be removed (see Rust erasers).

GENERAL KNIFE CARE TIPS:
Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:
✔ Use a wooden, plastic or rubber cutting board.
✔ After use, wash the knives and wipe them dry.
✔ Use a magnetic rack, knife blocks, or use protective knife sheath (saya).
✔ A good cutting technique is your best bet to prolong sharpness.
✔ Use sharpening stones to sharpen the knife.
❗️Don’t leave the knife in the sink. Wash it by hand.
❗️Don’t wash the knife in the dishwasher.
❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
❗️A knife is a tool intended for specific use: it’s not a can opener, screwdriver, trowel, wire cutter, hammer etc. Kitchen knives are meant for preparing food.
