    Default Back to ZDP-189

    Great, I found an old steel chart that I originally downloaded from a knife forum some time ago. It proves the point about possible fragility of ZDP-189 when compared to some other knife steels.

    I find four steels here that I have seen used on knives: 440C, ATS-34 (almost identical to 154CM), GIN-1 (found in nineties' Spydercos) and ZDP-189.


    As you see, ZDP-189 gets an A- for corrosion resistance, A+ for wear resistance and a B- for toughness. Is it "tough enough" - maybe yes, but some other steels are better. On the X and Y axes you can see that GIN-1 is all the way at the other end of the spectrum, scoring low on wear resistance (hardness) but better on toughness. GIN-1 would make for a better prybar than ZDP-189.

    It is interesting to see both 440C and ATS-34 there in the middle, with ATS-34 scoring a little better for both hardness and toughness. It makes sense, because it is more of a high-end steel. VG-10 is supposedly just a hair better than ATS-34 in most regards.

    So buy one and don't tell anybody that you have it. It's like how switchblades/automatic knives are illegal in a lot of places, but that doesn't stop online knife sellers from selling them. I bought one once and it came with a note that said, "This automatic knife may not be legal in your state. Check your local knife laws." I think I threw that note away with the box.

    Ohhhh ahhhh. Now i gots ta clean my bvds. Thanks Hollis.

    Great review Walker, and that chart is also a gem. I have been seeing on teh webz, that the best ways to sharpen the ZDP blades seem to be with a belt sander or diamond stones. Are you the same Walker as the one on BF or spyderforums?

    Hammer27, nice score on that SOG tigershark. I was "forced" to pick one up because they discontinued them, on top of moving the production of alot of their knives to taiwan and china. SOG blades from Seki are going to become less and less. *cries like a baby*

    I am not on Spyderforums! That's some other 'Walker'. I think it's Bladeforums where I am registered with the exact same name as here, but I haven't really written there much. They might also have other 'Walkers' there.

    Yeah, it makes sense that diamonds would work with ZDP-189.

    Thanks. I always wanted one of the originals and once they converted to the "2.0" with the ridiculous rasps, guard, and just general ugliness I couldn't handle it... so I broke down and finally bought one

    Henry's Fork, The Model 18 was a custom I got in 1985. The Smithsonian I bought at Randal in Orlando in 1992 & had a friend carve the moose antler & then installed it. Smithsonian was purchased with a leather washer handle.
