This is Camellia oil - the traditional protective oil for Japanese blades to prevent rust and corrosion. If you have a carbon steel blade (like our Koishi or Yuki ranges) then this is a nice addition to help keep them in tiptop condition. We have this specially imported from Japan.
Simply wipe a few drops over the blade before storing or after cleaning, it will give it a nice protective film and a little bit of a shine too. Camellia oil is tasteless and odourless and won't taint your food in anyway.
Samurai are meant to have used this same oil on their swords in times gone by, hence us nicknaming it "Ninja Lube" the instant it arrived.
Our aim is to measure everything as accurately as possible but some specifications (such as hardness for example) are provided by the manufacturer and therefore should be used as a guide only.
