I am not so sure how much a warranty with knives means these days. And with so much exculpatory language written into the warranties covering every aspect of goods purchased these days, I am not sure what too many of them are worth. I go through this when I have to call for warranty or parts on the many hand tools I have as a general contractor. This is how my normal warranty calls go: (manfacturer's name used interchangeably since they have the same level of service.)
Me: I was using myself, it was my personal tool in the truck, and when I took it out on the job to use it, the tool operated for a few minutes then stopped.
DeWalt/Milwaukee: Hmmmm.... what do you think happened?
Me: Don't know it just quit working.
DeWalt/Milwaukee: So you were using it?
Me: Yes, I was using it. It is a saw, and I took it out of the truck to use it as a saw.
DeWalt/Milwaukee: It looks like you bought the tool from an authorized DW/MKE dealer. Most Amazon sellers and most hardware and feed/tack stores are not. I see you are eligible for warranty work if that is what the problem turns out to be.. You can take it to the nearest authorized tool repair center near you, it is at XXXX XXXX.
Me: I know that shop. They have a $75 bench fee to check out the tool.
DeWalt/Milwaukee: That sounds cheap. If it is a warranty issue, we will cover the bench fee. If it is an issue caused by normal wear, normal use, abuse, age, accidental damage, incorrect usage or lack of maintenance, then you will pay the bench fees and the repair fees.
Me: Holy crap!! Your warranty really doesn't cover anything but maybe spontaneous combustion, does it?
DeWalt/Milwaukee: I don't know what that is sir, but the technician at the tool repair store will tell us what he finds. He/she will determine if it is covered under warranty. So I am paying $82 ($75 plus tax ) to see if my $120 saw is covered under your warranty? With all the conditions it has to meet to be considered a warranty issue along with my dollar investment, why wouldn't I just buy a new one?
DeWalt/Milwaukee: That's totally up to you sir. Is there anything else I can help you with? *silence* Wait... sir... did you say you were using this tool professionally? If you did, you voided the warranty on the product as it is not rated for professional use. (yeah.... you read that right.)
So, for me a warranty is a pretty subjective thing on anything I buy. As mentioned above, I agree with the idea that you will find out (in most cases) if something is not right with a knife pretty quick. Hopefully the knife you bought is from someone that will stay behind their product for a year or so till you can get the knife through its paces. But there is always a lot of grumbling here about companies big and small with good reputations that don't stand behind their product. Sure, fanboys jump in and claim how great their knife manufacturer of choice is, but still, lots of complaining, too. My biggest fear is that as all of us employers that are trying to keep staffed up go on down the road, our challenges of finding and training employees to do that kind of work (CS) will get worse. I am having problems on all fronts with all manufacturers these days, including with my own company.
Buy the best product you can that meets your requirements from a reputable dealer (ask me about my Queen knives that "were under warranty" as well as a couple of other traditionals when they shut their doors) and check out the product thoroughly before putting it in rotation. I think all the warranty issues will get tougher for all of us on all products as we get further into employment issues.
