They have a 5 year warranty so if it's within that, he's good to go.
Again...they never ask how old it is or for any paperwork.
There are no numbers on these things to track them back to their manufacturing date.
They have not changed how these hand tools have been made for years so they have no idea exactly how old they are...and don't really care.
Technically, a 5 year warranty, in reality I consider these lifetime warranty tools...just the same as Zippo products.
They have the same pride and attitude about their tools so Zippo's words work the same for this company as far as I am concerned...
"It works or we fix it for free".
If you mod it you lose your warranty, if you lose it you are out of luck but otherwise when you buy these tools you buy them for life.
I am sure they did the math long ago and decided to absorb the small percentage of broken tools that are returned to them yearly, it can't be that many and a stellar service reputation is worth way more to them than the money they would charge if they did stay to that 5 year limit.
George Lesche is no dummy, either...I am sure when he started his Predator company he just decided to do the same, put a 5 year warranty in the paperwork but just ignore it in real life.
If any of these tools were cheaply made and broke often a free replacement, (and return shipping), warranty would be a nightmare and very costly for these companies, luckily they are the opposite.
Not completely bulletproof or unbreakable but pretty close.
I am tough on my tools, I have owned 3 WW.MFG hand diggers and the 31" shovel for many reasons like how well they work under some very tough conditions but the most important is piece of mind.
And supreme value for the money, just in case.
