From Benchmade as of November 2018:
Each new Benchmade knife is packaged with written documentation of the Benchmade Limited Lifetime Warranty. Benchmade Knife Company, Inc. warrants that Benchmade knives purchased from authorized dealers will be free from defects in materials and workmanship. Benchmade will, without charge, repair or replace at our (Benchmade's) option, any knife purchased from an authorized dealer and returned for Warranty work that is found to be defective by Benchmade.
WHAT IS COVERED BY BENCHMADE
This Warranty covers replacement parts for genuine Benchmade products due to manufacturing defects.
The Benchmade Limited Lifetime Warranty only applies to genuine Benchmade products purchased from authorized Benchmade dealers. Knives purchased on the internet through discount websites, mail order outlets, or through any other unauthorized source, and knives which are determined by Benchmade to be counterfeit (see Counterfeit Goods Notice below), are not entitled to our warranty coverage.
Any Benchmade knife that is modified from its original factory condition will void the Lifetime Warranty of the knife. Benchmade is not responsible for parts or treatments added to or removed from the knife or for knives that are otherwise modified in any way, as these may cause the knife to function differently (and potentially less safely) than originally designed and intended.
WHAT IS NOT COVERED UNDER WARRANTY
This Warranty does not cover normal wear, damage caused by neglect, misuse or the failure to perform normal or necessary maintenance, disassembly of any knife by any person other than Benchmade’s Warranty department.
Do not use your new knife as a screwdriver, pry bar, chisel or punch. Do not throw your knife or use it for any purpose other than cutting. Do not disassemble your knife. Do not sharpen your knife on a power grinding wheel. Any of these acts will void your Warranty. MINIMUM CHARGE TO REASSEMBLE A KNIFE WHEN THE WARRANTY HAS BEEN VOIDED IS $20 PLUS PARTS.
Repair or replacement as provided under this Warranty is the exclusive remedy of the consumer. Benchmade shall not be liable for any incidental, reliance, or consequential damages or breach of implied Warranty on this product, including any damage to person or property. Benchmade’s liability under any circumstances is limited to the purchase price. Some states do not allow exclusion or limitation of incidental or consequential damages, so the above limitations or exclusions may not apply to you. This Warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
This knife has only one use, as a cutting tool. Benchmade’s knives carry no warranty except as expressly contained herein. Benchmade disclaims all warranties of merchantability and fitness for a particular purpose other than for use as a cutting tool. There are no warranties which extend beyond the description contained herein. Please review the Warranty information and proper knife care instructions provided with each knife.
