Hi Rawaz,

I use Camilla oil, which is also called tsuba or tea seed oil. This is a natural product which has been used on blades for centuries in Japan. Many people use a variety of oils made for guns and such, but I for one feel better about having something edible on my bkades, and potentially in any accidental cuts!

There are quite a number of threads on this that a quick search will turn up.

cheers,
cass
