It is likely to get rust on the blade made of steel if you do not care for it.
Especially most of Japanese traditional style knives are made of carbon steel, that is very sharp but easy to get rust.
To prevent rust, you need to do some adequate maintenance.
Don’t mind! It is very simple.
First, scrape or wash the knife cleanly with cleanser, and let it dry well by a dried towel.
Please don’t roast the blade over the fire. It causes degrade its sharpness badly.
If you need to sterilize your knife, we recommend hot water sterilization.
Second, put a thin layer of plant-derived oil on the blade.
If you have any question, please feel free to contact us anytime.
