I've used my zdp endura relativly hard and have not seen any big edge damage or chips. Its one of my favorite steels and I wouldn't hesitate to buy more zdp blades after what I've seen my endura do. I just read a thread here a few days ago, and a forum member used a zdp endura for work (construction) and he beat the living hell out of it. It did chip the edge, but nothing crazy. He smashed it with hammers and all sorts of torture.
