MulWark warrants its products for their useful life against defects in materials or workmanship. This does not cover tools that are improperly used, abused, altered or repaired, nor does it cover consumable goods like car fuse, knife blades, punches, etc. MulWark limited lifetime warranty also excludes incidental or consequential damages. Apart from above exclusions, deficient products will be replaced or repaired. We offer 30-Day Money Back Guarantee too. If you are not 100% satisfied with your MulWark tools, a 30-day return window is open for you. You can return the tool(s) within 30 days from the date of purchase for a full refund.
