I must be doing something extremely right as I've not experienced any burrs or microchipping to speak of with ZDP. In fact, I haven't noticed any appreciable drawbacks to this blade steel as yet and I've really been abusing my burgundy Caly Jr. As for nail catching after cutting cardboard, that's one of the things ZDP seems to excel AT! Very strange. We must live in parallel universes. Are you using a sandwiched model or the solid blade? May have something to do with it (although I wouldn't know why).
