Each new knife from Bon Centuri is covered with a 5 year warranty from the purchase date. The warranty covers manufacturing errors. The warranty does not cover normal wear and tear or damages caused by incorrect use of the knife, lack of care, negligence or accidents. The warranty does not cover wood products, such as wooden knife handles, as wood is a living material. Make sure you contact the Bon Centuri customer service as soon as a manufacturing error has been discovered. When contacting the customer service, please specify your name, address, order number, knife number and a detailed description of the issue at hand. We also need a photo clearly showing the stated defect. Bon Centuri will repair or replace knives that we find defective. The warranty only applies to Bon Centuri knives purchased directly from Bon Centuri. Second hand knives are not covered by our warranty.
