CIVIVI warrants its knives free from defects in material and workmanship to the original owner for the life of the product, with repair or replacement by the same model or one of equal value. An RMA is required before returning anything, and the warranty is voided by third-party repair or modification.
CIVIVI requires a return merchandise authorization before you send a knife back. Posting a knife without one is the most common way a valid claim stalls.
Start with the warranty page linked below rather than sending anything.
Third-party repair or modification voids the warranty outright. That is stricter than some competitors and worth knowing before you let anyone else work on the knife.
Also excluded: misuse and abuse, specifically naming throwing and prying, improper sharpening, and broken tips or clips resulting from misuse.
Coverage runs to the original owner. A secondhand CIVIVI is unlikely to be covered.
Warranty terms are set by the manufacturer and can change. The maker's own warranty page, linked below, is the authority. We repeat what it says; we do not extend it, and a retailer cannot promise coverage a manufacturer has not offered.
