Your Normandy knife is warranted for life under the following guidelines.
Treat the knife as a knife. Use of your knife for any purpose other than cutting is considered abuse and will void the warranty. It's not a screwdriver, chisel, pry bar, punch, fork, or any other tool. These are not designed for throwing.
Operate the knife as designed. Damage caused by abuse, neglect, misuse, accident, improper blade sharpening, introduction of foreign substances. Normal wear and tear including paint loss, fading, discoloration, or chips are serviceable but not covered under warranty.
We do everything we can to create raving fans of Normandy Knives -- we had a customer drop his knife in a fire and sent it in -- we took care of him! See the image below for what the burnt knife ended up looking like!
