Love the steel. I was doing a sharpening project on my ZDP Endura to get it the "perfect edge." I didn't get to finish (I needed the knife ASAP; I don't currently have a backup), but the knife was still reasonably sharp. I've been using it for 3 weeks and haven't sharpened it since (extreme box cutting sessions a few times a week), and it's still going pretty strong.
ZDP is great stuff.
