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.

This knife blade is convex on both sides in the tradition of the highly praised Japanese sword. This shape is both sharp and strong, and can still slice cleanly through a sheet of paper even after the punishment of chopping and cutting through dried bamboo. Using this special blade shape is an excellent way of allowing an edge to be thick without sacrificing any of its sharpness. This knife is of preeminent sharpness. This is a durable knife with strong cutting capabilities that will last for a long time. Even when used for rigorous cutting, the blade will not bite or catch thanks to its convex shape. Other knives will often bite or catch, and may acquire nicks if pulled out suddenly.

信"SHIN" in Japanese means "trust".

SHIN-ZDP FAQ Section

Q1: How durable is the hard-anodized aluminum handle on the SHIN?

A: The handle is crafted from high-grade A6063 aluminum treated with a heavy-duty hard anodization process. This coating provides excellent resistance to scratches, corrosion, and daily wear, while keeping the overall footprint lightweight and balanced.

Q2: Can I sharpen the Rockstead SHIN at home?

A: Because of the signature HONZUKURI convex grind and extreme 67 HRC hardness, we highly recommend against using standard flat sharpening stones or pull-through sharpeners. Doing so will damage the flawless mirror finish. Register your knife via the included serial number on Rockstead's official site to access their lifetime factory maintenance.

Q3: What role does the stingray skin inlay serve?

A: Aside from paying homage to traditional Japanese katana handles, genuine stingray skin (Samegawa) is naturally one of the toughest materials on earth. Its unique texture provides a secure, non-slip texture that locks into your palm, ensuring excellent handling even in wet conditions.
