I recently took my new ZDP Delica on hard duty and sliced my way through a bunch of plastic strapping, boxes, and pried a few big staples. I thought I would break it in and beat it up a bit so as not to ever have to worry again about marring the blade at the edge or anywhere else.

Surprisingly, I can't see any blemishes whatsoever from the trials I put it through. Has anyone else put the ZDP Delica through it's paces and what has been the result for you?

I'm extremely impressed with this solid ZDP blade.
 
I cut down a few cardboard boxes, and a lot of tape, mostly using the tip, at work. I might not have done much with it, but it didn't dull even a little. I was still able to shave hair on my arm with it, and easily slice paper without effort.
 
I used mine removing chipboard sub-floor which had been glued, nailed and screwed down to the plywood decking in an apartment where I work. In just a few minutes, the factory wire edge was toast, but it was still sharp enough to chew through some of the adhesive they had used. Once I got rid of the rolled burr, it was easy enough to get hair popping sharp again. The blade shows no other scratches or scuffs from that job or any of the other things I have used it for. Considering that my blades seldom remain pristine for more than a couple of hours, that is pretty impressive. I believe I like ZDP189 :D
 
I stored mine in a safe for a few weeks. It came out dull, droopy and depressed. It definately performs better if used. No scratches though.
 
I used mine to cut up some cardboard. I think that I may have hit a staple with it because the edge was nicked. I sharpened it back up and scratched the blade on the diamond stone that I was using. ZDP is an excellent steel and I can't wait for some other job to come along so that I can use it.

As Yablanowitz stated, I think the edge was nicked partially due to there being a wire edge on it from the factory; that wire edge is gone though, so I shouldn't have to sharpen the knife again for a couple of years or so. ;)
 
Those are not Charpy results - they are CATRA results.

Bear in mind that these numbers are the result of the way Spyderco heat treats these steels, and the numbers may end up different if someone else's heat treat is tested.

Thanks for the correction. I don't know why I wrote charpy when I meant CATRA.

For us it's about the only way to compare apples to apples. No one is implying perfection. They do seem about right when it comes to my experiences using the steels, sharpening and resharpening, use before dulling, etc.My experiences with ZDP 189 and S30V and VG10 were/are spyderco. 440C is other makers. Note that I have no experience with S90V or S125V. Joe L.
