Rockstead Hizen DLC Premium Folding Pocket Knife with YXR7 Steel

The Miniature Masterpiece of Unrivaled Cutting Performance

Named 肥前 (HIZEN)—after a historical province of old Japan—this exceptional pocket knife is the compact, highly refined counterpart to Rockstead’s legendary SHIN model. Do not let its pocket-friendly size fool you; the Hizen DLC is engineered with the exact same high-performance DNA, offering world-class cutting capability in a lightweight, daily-carry package.

Featuring Rockstead's iconic Honzukuri (Convex) blade grind and a diamond-hard DLC finish, this is a masterfully engineered tool built for the modern gentleman who demands absolute mechanical perfection.

Key Features & Innovation

• Signature Honzukuri Convex Edge: Modeled after traditional Japanese swords, the convex blade geometry eliminates the standard secondary bevel. This provides unprecedented strength behind the cutting edge, minimizing friction for an impossibly smooth cut.

• Ultra-Tough YXR7 Steel & DLC Protection: The core is forged from YXR7 tool steel, offering extreme structural toughness and impact resistance at an optimized HRc 65. To provide complete corrosion resistance and a sleek look, the entire blade is mirror-polished and sealed with a premium DLC coating.

• A7075 Hard Duralumin Handle: The handle scales are precision-milled from A7075 airplane-grade duralumin and finished with a hard-anodized coating. This ensures a feather-light carry weight (only 73g) while remaining incredibly rigid and resilient against impact.

• Perfect Ergonomics and Liner Lock: Designed with continuous curved lines, the handle molds effortlessly into the hand, providing a secure grip despite its compact footprint. Deployment is buttery-smooth, snapping securely into a rock-solid liner lock mechanism.
  

YXR7 Blade Introduction

YXR7 is a premium matrix high-speed tool steel manufactured by Hitachi Metals, renowned for its exceptional impact toughness and high resistance to chipping, even at an impressive hardness of 60-65 HRC. This makes it an ideal choice for heavy-duty, hard-use tactical blades that endure severe stress. However, as a non-stainless tool steel with lower chromium content, its primary disadvantage is poor corrosion resistance, necessitating a protective surface coating and diligent oiling. Additionally, its high hardness makes field sharpening a demanding task requiring specialized abrasives.

Frequently Asked Questions (FAQ)

Q1: What is the benefit of the YXR7 steel and DLC coating on the Rockstead Hizen?

A: YXR7 is an advanced matrix high-speed tool steel known for its extreme structural toughness and resistance to chipping, even at an incredible HRc 65. Since tool steels are prone to carbon oxidation, Rockstead treats the blade to a flawless mirror polish followed by a Diamond-Like Carbon (DLC) coating, ensuring total corrosion defense and exceptional surface slickness.

Q2: Can I sharpen the Rockstead Hizen myself at home?

A: Because of the signature Honzukuri convex grind and ultra-hard HRc 65 composition, sharpening with standard flat stones can alter the blade profile. For regular maintenance, stropping on leather with a fine compound is recommended. For major sharpening, it is best to utilize Rockstead's official restoration service.

Q3: Does this knife come with Rockstead's factory sharpening warranty?

A: Yes. All authentic Rockstead knives include a lifetime warranty and access to their legendary factory sharpening program in Japan. Simply register your knife on the official Rockstead website using the unique serial number on your product box, and original master craftsmen will restore your edge to a factory mirror-sharpness for life (owner only covers shipping).
