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.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eThis blade material was changed to ZDP189 clad steel in 2022.\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable data-path-to-node=\"3\" style=\"width: 100%;
