ZA-18 Steel Properties and Performance
ZA-18 steel isn’t your average shear material. Developed by Osaka Clad Co., Ltd in partnership with Aichi Steel Corp, this steel is specifically designed to meet the high demands of professional cutting tools. Let’s take a closer look at its composition, hardness, and how it performs in real-world salon environments.
ZA-18 Steel Composition and Structure
The secret to ZA-18’s performance lies in its carefully balanced formula. It contains 0.95–1.20% carbon, which provides hardness, and 17.00–18.00% chromium, which ensures excellent resistance to corrosion. 1.00–1.50% molybdenum adds toughness, while 1.80% cobalt enhances hardness even further.
Additional elements like 0.10–0.25% vanadium, up to 1.00% manganese and silicon, and trace amounts of phosphorus and sulfur help refine the steel’s grain structure and maintain its purity.
This precise combination not only delivers exceptional cutting performance but also ensures the blade stays sharp longer, requiring less upkeep.
Hardness Rating and Edge Retention
ZA-18 steel boasts a hardness rating of 61–63 HRC on the Rockwell Hardness Scale. This high level of hardness, supported by its carbon content, promotes carbide formation, which is key to its exceptional edge retention. In practice, this means it can withstand hundreds of uses without frequent sharpening.
For stylists, this translates to consistent performance throughout the day. The blade’s sharpness allows for clean, precise cuts with minimal effort, reducing hand fatigue during long sessions. The inherent hardness also gives the blade a slight "cutting aggression", enabling it to slice through hair fibers effortlessly.
ZA-18 Steel Performance in Daily Salon Work
Professional salons are tough environments for tools. Constant exposure to moisture, chemicals, and heavy use can quickly wear down lesser materials. ZA-18 steel, however, is built to handle these challenges. Its high chromium content forms a protective oxide layer, shielding the blade from moisture and chemical damage. This ensures the shears maintain their appearance and performance, even with frequent cleaning and exposure to styling products.
The steel’s thermal stability is another standout feature, keeping the edge sharp and consistent during extended use. This makes it ideal for precision techniques like point cutting, slide cutting, and texturizing, giving stylists greater control and expanding their creative options. Plus, with less frequent sharpening needed, professionals can spend more time focusing on their craft and less time on maintenance.
In short, ZA-18 steel combines durability, sharpness, and resistance to environmental wear, making it a reliable choice for stylists who demand top-tier performance from their tools.
Manufacturing Process for ZA-18 Steel Shears
Crafting ZA-18 steel shears is an art that goes beyond just using high-quality materials. Shihan Shears combines the time-honored craftsmanship of Japan with modern precision to turn raw ZA-18 steel into cutting tools that meet the demands of professionals. This process takes full advantage of ZA-18’s properties to create shears that excel in performance.
Japanese Forging and Tempering Methods
At the heart of every Shihan Shears ZA-18 steel shear is a forging tradition that has evolved over nearly 800 years. This heritage traces back to the ancient Japanese art of sword-making, which dates as far back as the fourth and fifth centuries AD. Each shear is crafted with a level of precision that no machine can replicate.
The process begins with heating ZA-18 steel to exact temperatures, altering its crystalline structure. Rapid cooling, or quenching, follows, forming martensite - a structure that gives the steel its impressive hardness and strength. The steel then undergoes a three-step heat treatment process: normalizing to even out the structure, quenching to harden the steel, and tempering to balance hardness with toughness. This ensures the blade maintains its sharp edge without becoming brittle.
This careful process guarantees excellent edge retention, allowing the shears to stay sharp through countless cuts while maintaining consistent performance.
Ergonomic Design with Lightweight Construction
Shihan Shears doesn’t just focus on exceptional steel quality; they also prioritize creating tools that feel like an extension of the stylist's hand. The manufacturing process ensures perfect weight distribution between the blade and handle, delivering a balanced feel during use. A lightweight design is a key feature, with thinner blades and reduced overall weight requiring less effort during cutting. This lighter build helps reduce hand fatigue, even during long hours of use.
Shihan Shears also incorporates offset handles and adjustable components to accommodate different hand sizes and cutting styles. This level of customization allows stylists to achieve both comfort and control, whether they’re performing intricate techniques like point cutting or tackling high-volume tasks in a busy salon.
Every step of the manufacturing process is aimed at maximizing the potential of ZA-18 steel while ensuring the stylist's movements feel natural and effortless. The result? A shear that not only delivers professional-grade performance but also supports long-term hand health and comfort.
