Chef Knife 215 mm — SRS13 49-Layer San-Mai | High-Performance PM Platform

Chef Knife 215 mm — SRS13 49-Layer San-Mai | High-Performance PM Platform

This Chef knife is built within FireForge’s high-performance powder metallurgy tier, positioned above the M390 Crown Series and below the ultra-high hardness ZDP189 platform.

It is engineered for professionals and advanced users who require increased edge retention without entering extreme hardness territory.

Engineering and Materials

The blade core is manufactured from SRS13 powder metallurgy stainless steel, selected for:

• Fine carbide distribution

• Stable hardness profile

• Predictable sharpening behaviour

• Improved wear resistance compared to conventional stainless steels

The core is vacuum heat treated to:

62–64 HRC working hardness

The core is clad with:

48 layers of SUS420J2 stainless steel (24 per side)

Total structural composition:

49-layer san-mai construction

Spine thickness: 2.4 mm
Edge geometry: 15° per side

Surface and Structural Finishing

The blade features a controlled polished finish combined with a hammered (tsuchime) texture.

This surface treatment:

• Reduces food adhesion

• Improves ingredient release

• Maintains corrosion resistance

The multilayer pattern is structural, not etched ornamentation.

Functional Performance

With a 215 mm blade and 2.4 mm spine, the knife supports:

• Push cutting

• Rocking motion

• Tip precision work

• General professional preparation

Weight: 235 g
Balance: forward-neutral

This knife is designed for sustained daily work, not display.

Handle Architecture

• Desert Ironwood construction

• High density and dimensional stability

• Natural moisture resistance

• Ergonomic profile

• No artificial weighting required
