STARK Special OV Co5% Black PRECUT 2.0/25mm

The STARK Special OV Co5 Black Precut is crafted from Cobalt 5% high-speed steel (HSS) with a black oxide coating that enhances durability and minimizes friction. Each piece is precisely waterjet-cut to preserve the steel’s original hardness and grain structure — making it ideal for high-performance tari blade production. Strong, consistent, and ready for garol brazing and edge grinding.

The GLG Extreme Cobalt Co5 is a high-performance high-speed steel (HSS) circular blade designed for demanding industrial cutting—and an excellent premium material for gaff knives (tari) requiring superior heat resistance and edge stability.

Manufactured using Cobalt-enriched HSS (Co5 / M35 equivalent), this material contains approximately 5% cobalt, enhancing red hardness, wear resistance, and structural stability at elevated temperatures. The addition of cobalt improves the steel’s ability to maintain hardness even under intense friction, making it ideal for high-speed and high-stress cutting applications.

GLG’s EXTREME series further elevates performance through precision grinding and advanced surface treatment, resulting in smoother cutting action, longer blade life, and consistent performance across demanding conditions.

🔥 Why Co5 (Cobalt HSS) for Gaff Knives (Tari)?

• Superior heat resistance – maintains hardness even under extreme friction
• Enhanced edge retention – stays sharper longer than standard HSS
• Improved wear resistance – withstands repeated impact and use
• Higher red hardness – ideal for high-speed and aggressive applications
• Stable microstructure – consistent performance and reliability

Compared to standard DMo5 (M2), Co5 offers better heat performance and longer edge life, making it a preferred upgrade for users seeking stronger, longer-lasting gaff knives.

⚙️ Ideal for:

• High-performance gaff knives (tari)
• Competitive and professional use
• Applications requiring extended edge life and heat resistance
