All Leatherman products are manufactured from 100% high-grade stainless steel (exception: screw bits for the tool adapter are made of tool steel). 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 components are strong, and the knives retain a sharp cutting edge.
Depending on what your Leatherman has been exposed to, there are several cleaning methods to consider.
Leatherman knife blades may be straight-edged, serrated, or both. Sharpening methods vary depending on the type of knife in your Leatherman product (note: serrated edges should not be sharpened in the same manner as straight edges).
