自己看吧．．．当然，尽管他测试了，但也只是一家之言．
ZDP-189 “It’s psychotically high in chromium and carbon, much higher than any of the standard high-carbon stainlesses,” he began.
“This is not a logical extension of the family of cutlery steels that are known. It’s an anomaly and it’s expensive.”
“It does three times what VG will do,” he said, “four times what D-2 will do if the D-2 is heat treated perfectly to 62 Rockwell, and when you get into something like the more standard steels like ATS-34 or 154-CM, we know that it’s [10 times better].”
To compound the mystery, ZDP can be hardened to an incredible range of about 68 Rc on the Rockwell hardness scale.
At that level, most steels would chip, break or downright shatter. According to Conable, though, not ZDP.
“We haven’t been able to prove it any weaker than the other standard steels,” he remarked. “In all the tests we’ve done looking for brittleness, we haven’t found ZDP more susceptible to chipping or breakage in any way.”
To test ZDP-189, William Henry Knives sent one of its model B15 folders with the steel to an independent source.
According to WHK’s Rick Thronburg, after 100 cuts through 1-inch manila rope and with the edge still cutting well, testing was concluded. By comparison, here is how some other steels performed in the same test: •440C: 15 cuts; •154CM: 18 cuts, and; •D-2: 30 cuts. “
At some point in the future, we will run the test again to see how far beyond 100 cuts ZDP can go,” Thronburg noted. “But for now, ZDP-189 so completely eclipsed the performance of conventional steels, we had our answer.”
