After using your knife, it is a good practice to clean and dry your knife (the entire knife, not just the blade). Even though our blades are made with corrosion-resistant stainless steel, prolonged exposure to the elements can cause the steel's surface to oxidize. Folding knives should be kept clean of debris, particularly the locking device on lock-blade knives.
For your convenience, Buck provides two superb knife care products. Clean Streak is a completely residue-free metal prep that's easy to use. Just spray and wipe-no rinsing required. Metal Brite is a polish that removes surface oxidation, rust, tarnish and sticky residues while leaving a protective coating. Both products can be found in Accessories in the Products section.
As an alternative, chemical solvents such as Acetone, nail polish remover, MEK, alcohol or paint thinner may be used to clean your blade. Use care with these solvents, as some, such as acetone, nail polish remover, white gas, or brake fluid may damage some Buck handles. Avoid harsh detergents that contain Chlorine (mostly powders, including some for washing dishes and clothes), which can accelerate corrosion of the blade steel. Avoid prolonged immersion in liquids (water, solvents, etc.). This can have a detrimental effect on not only the metal parts, but handles made of wood or other porous materials as well. Before using your Buck knife on food items, wipe clean with alcohol, or wash with hot soapy water and rinse clean. Remember to re-clean and lubricate your knife after the food job is done.
Periodically, and always after cleaning, apply a small amount of lubricant to the working parts of the knife, particularly the pivot points of a folding knife. Then apply a thin film of lubricant to the entire surface of the blade. This will help prevent surface oxidation and corrosion from moisture. In our Accessories section, you will find Wax Lubricant that is superb at lubricating, sealing and protecting knife blades and working parts.
Buck knives are designed for cutting. Using them for other purposes, such as throwing, pounding, prying, chopping or other purposes may create an unsafe condition and may void your warranty. Strong impacts or twisting forces may damage the knife or lock mechanism, and may result in the blade folding or otherwise failing during use. Any such use could result in severe injury. On lock blade models, always check to assure the locking mechanism is engaged prior to use. Keeping your blade sharp will also reduce risk of injury, as a sharp blade is safer than using a dull blade.
Self-repair of a Buck knife will void your warranty. It is for this reason that we do not sell parts for repair. If your knife needs repair, please send it to us. If the necessary repairs are covered under warranty, the work will be done at no charge. If the repairs are not covered under warranty, we will advise you of the cost and ask for your approval before doing any work. Payment is required before repairs are performed. For more information about what is covered by warranty, please refer to our Warranty section.
