ZDP189 Blade Introduction
ZDP-189 is a high-carbon, high-chromium powder metallurgy steel renowned for its extreme hardness, often exceeding 64 HRC, which delivers peerless edge retention and aggressive cutting performance. This performance comes at a cost; its massive carbide volume makes the steel notoriously difficult to sharpen and increases brittleness, posing a risk of chipping under heavy lateral impact. Furthermore, while technically stainless, its high carbon content necessitates diligent maintenance to prevent oxidation, making it a specialized choice for precision cutting tasks rather than rough, heavy-duty utility.
