The SOG Ultra XR delivers premium cutting performance with its CTS-XHP steel blade and lightweight carbon fiber construction. This folding knife combines advanced metallurgy with tactical functionality for professionals and enthusiasts who demand reliability. The TiCN coating provides enhanced corrosion resistance while maintaining the blade's razor-sharp edge retention.
What Makes This Different
The Ultra XR features CTS-XHP steel, a premium stainless steel alloy that outperforms standard 440C by 20% in edge retention testing. The cryogenic heat treatment process refines the steel's grain structure, creating a blade that maintains sharpness through extended use. Unlike basic folding knives with aluminum handles, the carbon fiber construction reduces weight by 35% while providing superior strength-to-weight ratio.
Key Features
- 2.8-inch CTS-XHP stainless steel blade with cryogenic treatment for maximum edge retention
