Tohji Kengata Shirogami #1 195mm (7.7")
- Knife Care
Tohji Kengata Shirogami #1 195mm is a multi-purpose Japanese kitchen knife, able to tackle any type of fresh—and cooked—produce, from vegetables to cuts of meat and fish. It’s a real minimalistic marvel fit for the contemporary Japanese knife purist. Adhering strictly to tradition, it’s forged out of Shirogami #1 steel and fitted with a magnolia wood handle. The kengata shape is a bit more unconventional, but it draws gracefully from the rich history of sword manufacturing in Japan – the name kengata literally meaning “sword-like”.
The kengata (meaning “sword-like”) shape is similar to the bunka, whose fundamental attributes are instantly recognizable: reverse tanto tip for precision work, wider profile and a slightly shorter blade length. It departs from the usual form, though, with a blade that isn’t as flat, but instead curves slightly towards the tip. This way, the knife can be rocked back and forth on the cutting board, allowing for a different cutting technique that some might miss with a traditional bunka. It is still great for chopping, though, as it is for preparing all kinds of meat and raw fish.
Shirogami #1 is a very pure steel, and therefore one of the best in terms of sharpening. For the same reason, blades forged from Shirogami #1 steel will be able to achieve an insanely fine sharpness and retain it for a long time as well. They will, however, need a little extra care and maintenance owing to the fact that the steel isn’t corrosion resistant, and will develop a patina overtime.

San-mai is a lamination method that is achieved by pressing two outer layers of steel onto the blade’s core, made from Shirogami #1 steel. This kind of construction enables the outer steel layers to serve as protection for the very hard—and therefore brittle—core, improving the blade’s toughness.
It has a double bevel (symmetrical) blade.
This knife sports a minimalistic migaki finish, meaning the blade has been polished and given a whetstone kasumi finish stretching from the shinogi line and over the kireha (cutting edge). The polished surface is adorned with a unique, hand chiseled kanji.
The blade is fitted with an oval traditional Japanese (Wa) handle, made out of magnolia wood and finished off with a beautiful buffalo horn 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.
