Thank you for contacting Taylor Brands concerning your LB7 knife. Unfortunately we do not repair the Uncle Henry knives (LB7). If you would like to send in your knife we can replace it for you. We do require a $6.95 warranty cost, this covers the replacement knife and mailing it to you. If you would like to send in your knife please see the attachment for complete warranty and mailing instructions. Any further questions please do not hesitate to contact me.
