I am no blade steel expert - but I am a knife enthusiast. I have been reading posts from various folks about ZDP-189. Some stuff I have gleaned:
1. The steel is so hard that one guy used his ZDP-189 Endura to scrape an aluminum block before changing out a gasket. He claims he actually shaved aluminum metal off with it - yet it was still razor sharp afterwards. Guess that's why they call it a "super steel".
2. Another claim - where a guy uses his ZDP-189 blade (back spine) to sharpen cheap knives made out of soft steel.
3. On the down side - another guy used his Spyderco Stretch, ZDP-189, to cut CATV wire and the copper core made a nice size chip in the blade (saw results in a You Tube video). So ZDP-189 is very brittle. He was using the factory edge - maybe a different bevel would have helped (?)
4. Numerous complaints say it will rust, pit, or stain easily if you are not careful.
5. Still more complaints that it takes a lot of effort to sharpen. Would probably help to have a sharpening system designed for very hard steel. Not sure the standard Spyderco sharpening system would handle it without buying additional rods.
The last three points have really made me hesitate to get a knife with a really hard "super steel".
