Located in Echizen City, Fukui Prefecture, **Ryusen Hamono** crafts this exquisite knife, incorporating the traditional techniques of **Echizen Uchihamono**.

This **Santoku knife** is made using **Chromax**, a hybrid material combining iron and stainless steel. While it is more resistant to rust than iron, it is slightly more prone to rusting than stainless steel. However, it develops a unique patina that cannot be achieved with other types of steel.

### **Knife Specifications**
- **Origin**: Echizen City, Fukui Prefecture (Echizen Hamono)
- **Type**: Santoku
- **Blade Length**: 170mm
- **Steel**: Chromax
- **Handle**: Black laminated wood

**Chromax** is a semi-stainless steel produced by Takefu Special Steel. The core material is **VG-1** and is clad with a steel equivalent to **SU410S**, forming a **three-layer composite steel**.

**VG-1** contains **5% chromium (Cr)**, making it significantly more corrosion-resistant than carbon steels like **White Steel** or **Blue Steel**. It is highly resistant to rust, boasts exceptional sharpness, and has outstanding edge retention. The name **"Chromax"** comes from the fact that chromium (Cr) has been added to the maximum level without compromising sharpness.

### **Chemical Composition**
- **C (Carbon)**: 1%
- **Mn (Manganese)**: 1%
- **Cr (Chromium)**: 5%
- **Mo (Molybdenum)**: 1%
- **V (Vanadium)**: 0.5%

The **hardness** of Chromax ranges from **HRC 58 to 61**. Over time, under certain conditions, the surface of the steel may develop a **dark patina**, but this does not penetrate internally.

Chromax is widely used in **high-end professional knives**, proving its reliability and performance. Experience the excellence of **Ryusen Hamono's craftsmanship** for yourself!
