Pour a small amount of Canola Oil in a small bowl. About 1/4-cup coats 2 to 3 dozen knives.
Using a clean paint brush, hold the knife by the blade over bowl and generously coat the wooden handle with oil. Allow any excess oil to drip back into bowl.
Wipe excess oil off of the wooden handle with paper towel.
Place knife on newspaper to allow oil to soak in and dry. Allow approximately 4 to 6 hours for the oil to completely soak in and dry before putting the knives away.
This process may need to be repeated once each year depending on how often you use the knives and your method of washing them.
