Chef Knife — Coreless Dual-Alloy Damascus (110 Layers) | Structural Lamination Series

Chef Knife — Coreless Dual-Alloy Damascus (110 Layers) | Structural Lamination Series

This 215 mm chef knife is built around a coreless Damascus structure, where the cutting edge is formed by the same laminated material that composes the entire blade. Unlike conventional laminated knives with a defined cutting core and outer cladding, this construction distributes the alloy structure uniformly across the blade cross-section.

The design emphasises material architecture and structural uniformity rather than extreme hardness or specialised powder metallurgy steels. The result is a balanced kitchen tool intended for controlled slicing and daily preparation tasks while also showcasing the metallurgical layering that defines the blade.

Within the FireForge range, this model belongs to the structural Damascus category, where the technical interest lies in the layered steel architecture and forging process.

Engineering and Materials

The blade is constructed from 110 alternating layers of 10Cr15CoMoV and 9Cr18MoV stainless steels.

Both alloys are widely used in professional kitchen cutlery due to their balanced mechanical properties.

10Cr15CoMoV

• Chromium-rich stainless steel

• Balanced corrosion resistance and toughness

• Stable edge behaviour under regular sharpening cycles

• Moderate carbide structure supporting predictable wear

9Cr18MoV

• Higher carbon and chromium content

• Improved hardness potential

• Increased wear resistance compared with standard stainless alloys

• Strong corrosion resistance

In this blade architecture, the steels are forge-welded and folded repeatedly, producing a layered matrix rather than a separate core and cladding system.

Because the edge is formed directly from the layered material, the blade exhibits homogeneous wear behaviour across the cutting surface.

The operational hardness is stabilised at approximately:

60 ±1 HRC

This hardness level is intentionally selected to maintain:

• structural durability

• resistance to chipping

• predictable sharpening response

rather than pursuing maximum hardness values.

Manufacturing Process

The layered billet is produced through repeated forge welding and folding cycles, progressively increasing the layer count until the final 110-layer structure is achieved.

After forging:

1. The blade profile is ground and tapered from a 2.1 mm spine thickness toward the cutting edge.

2. Heat treatment establishes the final hardness and structural stability.

3. A cryogenic stabilisation stage reduces retained austenite and improves dimensional consistency.

4. The Damascus pattern is revealed through controlled acid etching, exposing the contrast between the two steels.

The surface pattern reflects the forging sequence and is therefore a by-product of the lamination process, not an applied decoration.

Functional Use

The blade geometry and weight distribution support:

• vegetable preparation

• slicing boneless proteins

• general kitchen tasks

• controlled push and draw cuts

The knife is intended as a balanced working chef knife with layered steel construction, rather than a high-hardness specialist blade.
