The SOG Altair FX delivers precision cutting performance with advanced metallurgy and ergonomic design. This fixed blade knife combines CPM 154 stainless steel with TiCN coating for superior edge retention and corrosion resistance.

What Makes This Different

The Altair FX features cryogenically treated CPM 154 steel, a premium powder metallurgy stainless that outperforms standard 440C by 15-20% in edge retention testing. The TiCN (Titanium Carbo-Nitride) coating adds surface hardness up to 85 HRC while maintaining the blade's flexibility. Unlike basic tactical knives with simple heat treatment, this blade undergoes sub-zero tempering for refined grain structure and enhanced toughness.

Key Features

  • 3.40" CPM 154 stainless steel blade with cryogenic treatment for maximum edge retention
  • TiCN coating provides superior corrosion resistance and reduces friction
  • Squid Ink Black GRN (Glass Reinforced Nylon) handle for lightweight durability
  • Clip point geometry optimized for precision cutting and piercing tasks
  • Satin finish blade maintains sharpness while resisting glare
  • Full tang construction ensures structural integrity under stress
  • Includes custom-fitted sheath for secure carry and blade protection
Field testing demonstrates consistent performance across temperature ranges from -20°F to 140°F. The CPM 154 steel maintains its edge through extended cutting sessions while the ergonomic handle provides secure grip in wet conditions. Professional users report reliable performance in tactical applications, outdoor work, and precision cutting tasks where blade retention matters.
