Uh, I guarantee their legal team is far more powerful than yours. What they will probably do (as I have heard from others) they will offer a trade in credit towards a new box.
A garage down the street from me had the Snap On shop equipment truck there today, I stopped and talked to the CS rep and sales guy on the truck, they told me that the warranty has fine print, that basically says that SO reserves the right to rescind any warranty on any item at anytime. This is not to protect against abuse but a way to get out of warrantying items long past their production era or useful lifetime.
To me that's just a BS, its either a lifetime warranty or its not. I have the owners manual from my last four boxes here, those warranties have all sorts of disclaimers but none saying that they can rescind the warranty at anytime. It does say that to get a full copy of the Snap On tool warranty to right to their Kenosha, WI address for a copy. So they leave an opening legally in that unless you got a copy of that warranty in hand at the time of purchase and it clearly did not state that they could toss the warranty out the window if they so please, then you wouldn't have much to stand on legally.
I remember when they decided to drop the drill bit warranty, I had just bought a set of bits in 1989, the dealer came in with a sheet stating that bits would no longer be covered for breakage, and on the reverse side it gave a page full of fine print and legal jargon about why they were and could do this.
I gave the bits back and got a refund. I bought a set from Mac tools that were guaranteed. Its one thing to drop a warranty but when your paying an inflated price just for that warranty, and they then take it away, its theft in my eyes. After a few deals like that I started to look at Snap On differently, I bought only what I had to for either quality or functional reasons. Things like sockets, ratchets, wrenches, and some specialty tools I bought from Snap On because there was a clear difference, but on tools like bits, files, chisels, and blades, I bought with cost and warranty in mind. Even with this in mind I still ended up having close to $80K in Snap On tools in my boxes, and probably half again of that in other brands. I worked on multiple brands over the years, so my tool set was pretty diverse. I also worked two jobs for 20 years, meaning I kept two separate tool sets at two different shops. It also meant I had two Snap On dealers to choose from.
