No offense to Jerry but that summary is marketing hype, plain and simple. There have even been knives whose pictures were posted in bladeforums, where the edge chipped or tore. It's not that tough to do, really - any situation where the edge binds in a material and the blade torques, such as having lots of momentum from a chopping swing, can shear out a bit of fine edge.

The chip I saw had absolutely nothing to do with the zilla itself, as far as I can tell - it's just one of those one in a thousand chance happenings. Chop enough, instead of putting your blades in a safe, and you'll see it too - most won't even bother to mention it, as it's usually very minor damage, and easily sharpened out. And again, anyone who is using knives regularly is sharpening them regularly too.

I only mention this very minor damage here to point out that, while a very fine steel, INFI isn't magical, an no amount if very strong marketig statements can make it stop obeying the laws of physics.
