The ol' 'lifetime warranty' thing is a bit of a trap. You only have think of tools with a 'lifetime warranty', yes some have a true 'lifetime warranty', but if you read the fine print on most, you'll find otherwise. A lot of manufacturers consider only a few years to be a lifetime! It all comes from the integrity of the metal in question, and the way it is utilised.

So yeah, it could be until the warranty runs out. How many mobile phones seem to die at the end of the contract? Coincidence???
