Satin TiNi (Titanium Nitride) Cryo CPM 154 Stainless Steel • Field Green GRN Handle
Model: SOG17790357 • UPC: 729857013604
Lightweight, low-profile, and built to work—the SOG Altair FX (SOG17790357) delivers everyday cutting performance in a compact fixed-blade format you’ll actually carry. Its 3.40-inch plain-edge blade is crafted from CPM 154 stainless steel, then cryogenically treated to enhance edge stability and wear resistance. A sleek Satin TiNi (Titanium Nitride) finish lowers friction through material and adds an extra layer of corrosion and abrasion protection. The Field Green GRN (glass-reinforced nylon) handle locks confidently into your hand with traction texture and contouring that stays secure in wet or gloved conditions.
From trail meals and camp chores to fishing, hunting support, and daily box duty, the Altair FX is a go-anywhere tool with premium steel, smart ergonomics, and clean, efficient cutting performance.
Why the SOG Altair FX Stands Out
Cryo CPM 154 Stainless Steel
A premium stainless renowned for excellent edge retention, toughness, and corrosion resistance. SOG’s cryo treatment refines the steel’s microstructure, helping the edge stay keen longer under real-world loads.
Satin TiNi Protective Finish
Titanium Nitride adds abrasion resistance and reduces drag for smoother slicing through rope, cardboard, plastics, and food—while the satin sheen cleans up quickly after hard use.
Plain-Edge Precision
A straight, un-serrated edge provides clean, predictable cuts and easy field sharpening with pocket stones or rods.
Field Green GRN Ergonomics
Glass-reinforced nylon scales keep weight down without sacrificing strength. Texturing, indexing, and subtle jimping promote a secure, fatigue-reducing grip in the rain, heat, and cold.
Compact Fixed-Blade Confidence
No pivot to clog with grit, no lock to fail—just instant access and dependable strength in a compact, EDC-friendly size.
Always follow local laws regarding knife carry and blade length.

Performance You’ll Notice
Sharper for Longer
CPM 154 holds a working edge impressively well—so you sharpen less and cut more.
Smoother Slices
The Satin TiNi finish lowers friction, gliding through fibrous material and food with less effort while resisting scratches and staining.
Locked-In Control
The GRN handle’s traction and contouring keep your hand planted for safer push cuts, notching, and precise tip work, even when wet or wearing gloves.
Ideal Use Cases
Trail & Camp: Food prep, cordage, tent stakes, feather sticks, and general camp chores.
Fishing & Boating: Trim braid/mono and prep bait; stainless steel stands up to damp environments.
Hunting Support: Light processing, game-bag prep, and campsite tasks.
Everyday & Shop: Break down boxes, cut strapping/hose, trim garden ties—whatever the day brings.
Carry & Setup Tips
Position for Access: Mount or stow the knife where you can draw safely with your dominant hand—on belt, pack strap, or inside a kit.
Retention Check: Ensure your chosen carry solution secures the blade yet releases cleanly for consistent, one-hand access.
Practice with Gloves: Rehearse draw and stow motions to build real-world muscle memory.
Care & Maintenance
Clean & Dry: After exposure to saltwater, acidic foods, or game fluids, rinse and dry thoroughly.
Edge Touch-Ups: CPM 154 responds quickly to ceramic or diamond stones; finish with a light strop to restore razor bite.
Protective Film: Although corrosion-resistant, a thin coat of food-safe oil on the edge helps in humid or marine environments.
Hardware Check: Periodically snug any handle/carry-system fasteners after heavy use.
