Defects due to materials or manufacturing are repaired or replaced. Defects due to abuse or unreasonable use are not covered and the product is returned to the customer. In practice, Leatherman's interpretation of "normal use" is broad - a firefighter's Wave submitted with loose pliers, a broken blade, a dull serrated blade, a worn file, and missing bits was accepted for repair and replaced with a remanufactured unit, which gives a reasonable indication of how the warranty is applied. Accessories and sheaths are not covered by the 25-year warranty, except for the Adapt Kit, Ratchet Driver, and Premium Leather Sheath, which carry a 2-year limited warranty.

Leatherman products are designed to be disassembled by factory-trained technicians only. Repaired tools are reassembled with the pivot posts cemented to ensure proper tension for optimum tool performance. Attempting to disassemble a Leatherman tool yourself may result in lost components and compromised tool functionality, and may also void your warranty protection. For maintenance, rinse under warm water, dry thoroughly, and apply a drop of light oil to the pivot points — that is the extent of what Leatherman recommend doing at home.

Yes. All multi-tools and knives featuring MagnaCut steel blades come with a free sharpening service. Submit the sharpening service form, send the product to Leatherman, and their blade specialists will return it to factory sharp — with return shipping covered. This applies to the ARC and Wave Alpha. It is a separate service from the warranty claim process and can be used whenever the blade needs a factory restore rather than a field touch-up.
