Is it the first knife that doesn't wear because of sharpening? / sharpening off any damage?
Warranty is nice, but it only helps for factory defects..
And a knife for real "use" will be broken anyway, despite of it's quality.
It simply wears, eats up sand, takes damage and metal fatigue (if you use it as a mini crowbar) etc..
That's also the reason why you never have enough knives.

Sure, someone may one day kill me with my own gun.
But they'll have to beat me to death with it because it's empty.
A computer once beat me at chess, but it was no match for me at kick boxing.
