I craft each one of my knives with durability and performance in mind. With proper care, each one should last a lifetime. Should your knife purchased from us ever fail due to defect in craftsmanship, please return it along with the issued certificate tha you were given with your knife purchase and I will repair or replace it free of charge. If it is evident that the knife has been abused warranty would be voided. Each knife is designed to be durable and last a lifetime however using it for other purposes then its designed for can lead to damage. (ie: Using as a prying tool, screw driver ect.)
