IF WELL-MAINTAINED, A LEATHERMAN TOOL CAN LAST A LIFETIME
RUST AND CORROSION
All Leatherman products are manufactured from 100% high-grade stainless steel. (Exception: Screw bits for the tool adapter are made of tool steel.) But stainless steel is not rust proof; it is corrosion resistant. Depending on the mix of metal alloys, stainless steels may be highly corrosion resistant and relatively soft (like kitchen flatware), or they may be somewhat corrosion resistant and quite hard. Our products are fabricated from the latter type, so your tool and gear components are strong and the knives retain a sharp cutting edge. Consequently, corrosion can occur in the absence of proper maintenance. Your Leatherman product should be cleaned, dried and re-oiled periodically to inhibit rust and corrosion. This is especially true if you use it in a damp or marine environment. After cleaning, re-oil pivoting areas with a light machine or penetrating type oil. Buff stained surfaces with a polishing cloth or non-metallic abrasive (e.g., Scotchbrite pad or soft bristle brush). Do not use WD-40 as this will corrode washers on our tools.
Leatherman products feature knife blades that may be straight-edged, serrated, or both. Sharpening methods vary depending on the type of knife in your Leatherman product. Note that serrated edges should not be sharpened in the same manner as straight edges. Straight-edged blades can be sharpened using any standard equipment, including whetstones, rods, and various kits. To sharpen a serrated blade, be sure to use a sharpening system specifically designed to accommodate serrated edges. A proper sharpening method will maintain the curvature of the serrations. Sharpen serrated blades only on the edged side; sharpening the flat (back) side of the knife will cause the serrations to wear away, reducing the knife's effectiveness.
Depending on what your Leatherman has been exposed to, there are several cleaning methods to consider.
- If your Leatherman has been exposed to salt water or marine environments, it should be thoroughly rinsed in fresh water, dried, and lubricated with a water-displacing product. If stains or rust spots appear, refer to the Rust and Corrosion section above for removal tips.
- If debris or sticky substances have accumulated between the blades, your Leatherman may also be cleaned in a mild solution of detergent and water.
- To remove tar and similar substances, clean your Leatherman with turpentine or other mineral spirits. Do not use chlorine products.
- After cleaning, dry your Leatherman and apply a multi-purpose lubricant and corrosion inhibitor (CRC 3-36) to force out moisture trapped in the joints. This also helps protect the tool from further corrosion and sticking.
