Care & Maintenance

Care & Maintenance

For more than a hundred years, consumers have trusted Ballistol to lubricate, penetrate, clean, protect, and preserve their, leather gear, wood, metal surfaces, and more.

With an astonishingly wide range of applications, this environmentally friendly multi-purpose oil has become an essential tool for shooters, hunters, fishermen, and handymen all over the world.

To simplify the initial care and maintenance process, we’ve partnered with Ballistol to include a single use wipe with each Castillo knife. We absolutely love this stuff and it’s our suggested cleaning and protective solution for your knife handle, blade and leather sheath. Simply remove the wipe from the package and lightly coat each surface.

Wood Care

Ballistol maintains, protects, preserves, and rejuvenates unpainted wooden surfaces. It regenerates natural wood, brings out the wood grain and protects the handle from drying out and cracking. Keep all wood handles away from prolonged exposure to moisture and heat.

Leather Care

Leather that is frequently exposed to moisture or high humidity will become hard and brittle if not treated correctly. Ballistol will keep all smooth leather soft, and will effectively protect leather against the effects of water, insects and mold. If properly cared for, your leather sheath will break-in nicely and form a beautiful patina from every day carry.

Blade Care

Castillo blades are made from Sandvik 14C28N steel which is naturally corrosion resistant. Using a light coat of Ballistol on the blade will form an additional protective layer on the surface to help prevent rust. Ballistol can also be used to clean and lubricate the pivot points which will help ensure proper function.


Each Castillo knife includes a USA made, 320 grit, bonded ceramic sharpening stone. It’s recommended to apply Ballistol oil (not included) to the stone prior to use. Water can also be used as well. The hollow grind of your Castillo knife is concave, meaning that the sides curve inward until they meet. This creates a razor-sharp edge that requires maintenance over time and we suggest sharpening your knife before it becomes dull. Sharpen with caution and at your desired angle. A dull knife can be a dangerous knife and if you aren’t comfortable sharpening your knife on your own, we recommend contacting a professional sharpening service.
