We understand that many customers will disassemble their knives for cleaning and maintenance, and we’re glad that you take such good care of your knives! Your warranty will remain valid if you are careful not to damage any parts during disassembly or reassembly. Warranty does not cover stripped screws or lost parts. We’re happy to provide replacement parts for a small fee if we have any available, but we can’t guarantee to have the part you need on hand.
