Unryu Original No.20
Unryu Original No.20 is a smaller, hand-made Japanese knife with a damascus pattern and a laser-sharp blade designed for extremely precise and delicate cuts. The length of the whole knife is 180mm (7.1"), of which the blade is 60mm (2.4").
STEEL AND CARE:
The blade is hand-forged from Aogami #2 with a hardness of 61-62 HRC. The entire surface of the knife (blade and handle alike) is adorned with an interweaving damascus pattern, poetically dubbed "the movement of clouds in the wind". The blade is single beveled, the blade and the handle both made of steel. The core and outer layers of the knife have a smaller percentage of Chromium, which means that this blade will get some patina with use over time. The knife needs to be taken care of though, it should not be left wet and have oil applied to the blade every so often - we recommend using Ballistol oil.
As this Kiridashi is a bit smaller and finer, it is recommended for internal use for fine upholstery, cutting stitches on leather and fabric, opening smaller packages, office tasks - opening letters, packing.
Unryu literally means "Cloud Dragon Paper" and could refer to a handmade natural fiber paper, translucent and very gentle, or a mythical creature in Japanese folklore.

☝️ 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.
