A must have for protecting carbon steel. Camelia oil is made by cold pressing the seeds of the wild Camelia Japonica flower. Used by many as a skin moisturizer and hair conditioner.

Apply a very small amount and lightly wipe on with a lint free towel to ensure no further oxidation on your clean metal. Wash off before using your knife for safety.
