I heard that the ps (1/2 serrated) version has been dropped and zdp has a rc of 64-65, making it brittle and prone to rust.
The plain and serrated are still in the lineup.
Any thoughts?

I don't think it's excessively prone to rust. A few months ago I took mine to the beach, spent about two hours in and out of the water before I was able to rinse the knife with fresh water. The only corrosion was a small amount of surface rust where the liners contact the tang when the knife is closed.

After some initial chipping that may have been part of the learning curve I had with sharpening I haven't seen much of anything that leads me to believe it's brittle. Here's a thread over at BF that has some input and pics of a hard use ZDP E4. Link.

I think it's a good knife, I'd try to find one of the newer FG ZDP models that are working into the pipeline. The saber ground models are a little thick for my taste after getting used to the thin grind of the FRN Stretch.

Well, that makes me feel so much better about pulling the trigger on the ZDP endura that's in the mail at the moment.

Hmm... I've cut oranges with ZDP-189 and left it for about 15-20 minutes without any problem. Then I cut a weed down and left the juice on for about 45 minutes. The blade got spots and one section of permanent discoloration.

It's a good steel, still. It's hard, so burring isn't a problem at all. It does take a bit longer to sharpen, though.

Thanks for the info and link guys.

For sharpening, I have found that light pressure is better for ZDP189, because I have formed burrs with ZDP that were challenging to remove later. Nice product that holds a nice fine edge for a very long time.

Also worthy of note... ZDP-189, because it is so hard, doesn't scratch easily. Get this: I've cut hundreds of boxes down with my ZDP Delica for 3 months. I've had my VG-10 FFG Delica for almost 2 weeks, now, and I've cut down maybe a little over a dozen boxes. It already has more scratches on the blade than my ZDP Delica lol

As far as corrosion goes, even with its 20% CR, ZDP seems to behave much like a semi-stainless like D2. It isnt really a problem, it just needs a little attention. Make sure to keep it clean, (after cutting messy things) and you are golden.
