This is completely untrue - BKRT's warranty is one of the worst available. What their "lifetime warranty" often means in practice is that if you buy a botched knife with an edge that chips - one of the commonest BKRT problems - then they'll regrind it until they reach steel that hasn't been ruined by over-aggressive grinding. This can mean that you lose a lot of steel and have a knife that has nothing life the geometry you wanted and has almost no resale value. By comparison, Essee and Busse simply **replace** failed knives with new ones - generally, even when the knife failed for reasons other than poor workmanship.
