Rockstead HIGO II X-FCF-ZDP Dark Matter Copper — Forged Carbon Fiber & Titanium ZDP-189 Folder

This Rockstead HIGO II X-FCF-ZDP combines Rockstead’s mirror-polished Japanese blade geometry with Dark Matter Copper carbon fiber and a precision-machined titanium frame. Its 89 mm Honzukuri blade uses an ultra-hard ZDP-189 core clad between protective VG-10 stainless steel layers. The exact knife carries registration number F-HFCFZ L1742 (DMC) and includes its original Rockstead wooden presentation box and specification sheet.

Rockstead HIGO II X-FCF-ZDP Model Overview

The HIGO II X-FCF-ZDP represents an elevated variation of Rockstead’s established HIGO folding-knife platform. This Dark Matter Copper configuration surrounds the knife’s titanium structure with richly patterned carbon fiber containing copper-colored strands and inclusions.

Rockstead describes its knives as “factory custom” pieces because the company combines high-tolerance machining with extensive hand finishing. Consequently, the HIGO II X offers the mechanical consistency of precision manufacturing while retaining the finishing standards collectors associate with handmade custom knives.

Collectors can compare this model with other available direct from maker collector-grade pieces or explore WBKC’s broader selection of premium folding knives.

Mirror-Polished ZDP-189 and VG-10 Clad Blade

The blade places a high-hardness ZDP-189 cutting core between outer layers of VG-10 stainless steel. This clad construction supports the cutting performance of ZDP-189 while adding more corrosion-resistant material along the blade’s outer surfaces.

The specification sheet supplied with this exact knife records the ZDP-189 core at 66.0 HRC and the VG-10 cladding at 60.7 HRC. Meanwhile, the blade measures 89 mm, or approximately 3.50 inches, with a thickness of 0.125984″.

Rockstead finishes the primary bevels to an exceptionally reflective mirror polish that continues toward the cutting edge. In contrast, the upper blade flat carries a subdued finish that clearly displays the Rockstead logo, HIGO II markings, and registration number L1742.

Honzukuri Dual-Convex Blade Geometry

The Rockstead HIGO II X-FCF-ZDP uses the maker’s Honzukuri blade geometry. Inspired by traditional Japanese sword construction, this profile places a continuous convex surface on both sides of the blade rather than using a conventional flat or hollow grind.

Rockstead progressively changes the blade angle from approximately 30 degrees through the middle portion to roughly 24 degrees near the tip. A continuous transition joins those angles instead of creating abrupt grind changes.

This geometry gives the blade a strong central structure, a highly refined edge, and a distinctly smooth cutting feel. The elongated point, raised central ridge, polished bevels, and precisely formed tip also create the unmistakable visual character associated with Rockstead folders.

Collectors comparing different grind styles and construction methods may find tips in the how to choose a custom knife guide helpful.

Dark Matter Copper Carbon Fiber and Titanium Handle

Dark Matter Copper carbon fiber covers both sides of the handle. Its black and charcoal base contains irregular copper-toned patterns that shift visibly as lighting and viewing angles change. Because the material pattern forms organically, each scale has its own visual arrangement.

Beneath the carbon fiber, Rockstead uses a rigid titanium handle structure with warm copper and bronze coloration along its perimeter. The exposed titanium edges visually frame the darker scales and connect the handle to the knife’s copper-colored liners and hardware.

A generous lanyard opening sits at the handle’s rear. Meanwhile, the carefully shaped handle profile provides a smooth forward transition into the pivot and blade.

Precision Construction and Frame-Lock Mechanism

Rockstead builds this folder around a titanium frame-lock mechanism. The lock bar engages the blade tang from the clip side, creating a direct and structurally simple locking system.

A precision pivot, dual thumb studs, internal stop pin, machined standoffs, and closely fitted handle components complete the assembly. Jimping along the exposed frame and blade spine adds tactile indexing near the pivot and rear of the handle.

The supplied specification sheet identifies the pocket clip as SUS420J2 stainless steel. Rockstead mounts it for right-handed, tip-up carry and marks it “Made in Japan.”

Opening, Carry, and Functional Features

Dual thumb studs provide controlled manual opening from either side of the blade. Once deployed, the frame lock secures the blade while the contoured handle offers a streamlined grip without aggressive protrusions.

The slim pocket clip keeps the carry profile clean, while the carbon fiber reduces weight compared with an all-titanium handle of similar dimensions. The knife measures approximately 8.50 inches overall and weighs 133 grams, or about 4.69 ounces, according to the documentation supplied with this exact example.

Rockstead HIGO II Dark Matter Copper FAQs

What blade steel does the Rockstead HIGO II X-FCF-ZDP use?

This knife uses a ZDP-189 cutting core clad between VG-10 stainless steel layers. The supplied specification sheet lists the ZDP-189 core at 66.0 HRC and the VG-10 cladding at 60.7 HRC.

What is a Rockstead Honzukuri blade?

Honzukuri is Rockstead’s dual-convex blade geometry inspired by traditional Japanese sword construction. Both sides curve continuously toward the cutting edge instead of using conventional flat bevels.

What is Dark Matter Copper carbon fiber?

Dark Matter Copper is a carbon-fiber material with irregular copper-colored strands and inclusions. The pattern changes across each scale, giving individual knives a distinctive appearance.

What locking mechanism does this Rockstead use?

The HIGO II X-FCF-ZDP uses a titanium frame lock positioned on the pocket-clip side of the handle.

How large is the Rockstead HIGO II X-FCF-ZDP?

The knife measures 8.50″, overall. Its blade measures 3.50″ with a blade thickness of 0.125984″.

How much does this exact knife weigh?

The original specification sheet supplied with registration number L1742 lists the weight as 4.69 ounces.

What comes with this Rockstead knife?

This example includes the original Rockstead wooden presentation box and manufacturer specification sheet bearing registration number F-HFCFZ L1742 (DMC).

Where was this Rockstead knife made?

Rockstead manufactured this knife in Japan. The company operates in Sakai, Osaka, and the pocket clip is marked “Made in Japan.”
