Our Element Label Tsubaki oil is formulated specifically to be used used for prevention of rust on high-carbon steel knives and traditional Japanese blades. Apply our 70:30 mix of mineral and camellia oil when you’re storing your knives for an extended period (like for a vacation). If you live in a very humid environment, apply the oil on your blades more frequently to combat rust. Use a few drops of oil on your blade and apply evenly, making sure not to miss any spots. Wipe off residue with a soft towel. Available in large, 4oz/120ml and small, 2oz/60ml.
