Tojiro Kiritsuke Shirogami 240mm (9.5")
- Knife Care
Tojiro's Kiritsuke Shirogami is a large entry-level knife that will bring you into the mystical world of carbon reactive Japanese knives. Shirogami White steel #2 will change color, get patina, and, if not taken care of properly, develop rust. The advantage of Shirogami steel is the ability to be sharpened to a very sharp edge quite easily.
Kiritsuke knives are hybrids between the traditional Japanese knife yanagiba (slicer knife, mostly used for sushi) and the usuba (knife specialized to cut vegetables), meaning they can be used for all sorts of tasks in the kitchen, from making sashimi, slicing through ribeye, to chopping veggies. Japanese traditions only allow the Executive Chef to wield this knife. But since we're not in Japan, we can bypass the strict rules and enjoy this nice kiritsuke even if we are not the head chef (yet). We won't tell anyone.
The knife was left an unprocessed black patina on top of the blade, called kuro-uchi, which gives it a raw, unfinished look. The traditional Japanese D-shaped handle is made of magnolia wood and boast a plastic ferrule.
Overall, this kiritsuke offers a great price-performance ratio for users interested in carbon reactive, high maintenance kitchen knives.
Tojiro is one of the top 5 largest Japanese kitchen knife manufacturers. They are renowned across Japan and internationally for their top-quality knives for a reasonable price. Tojiro's focus on advanced technologies, together with their insatiable dedication for constant improvements of their knives and materials, makes Tojiro's knives a must-have in any kitchen. Tojiro's main focus? Sharpness!
A big bonus is their great team which we are always very eager to meet and talk to! 😊

☝️ 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.
