SOG-TAC Auto Compact – 2.94" Automatic Knife, Straight Back, Partially Serrated, Black TiNi Cryo D2 / Black Micro-Textured Aluminum
(Model SOG15380857 • Alt Ref SOG-15-38-08 • UPC 729857011730)
Fast, compact, and ready for real work. The SOG-TAC Auto Compact packs a 2.94" straight-back blade of Cryo-treated D2 tool steel with a Black TiNi (Titanium Nitride) coating into a pocket-friendly chassis you’ll actually carry every day. A bitey partial serration chews through strap and webbing, while the plain section handles clean slices. The micro-textured, anodized aluminum handle keeps weight down and grip up, and a low-profile pocket clip makes discreet carry simple. Press the button and the blade deploys automatically with authority—then locks up solid until you close it.
If you want a proven, duty-capable automatic that disappears in your pocket but shows up for work, the SOG-TAC Auto Compact (SOG15380857) is built for the job.
Legal Note: Automatic knives are regulated in many regions. Know and follow your local laws regarding purchase, carry, and use.
Why the SOG-TAC Auto Compact Stands Out
Cryo D2 Tool Steel (Edge Life + Toughness)
High-carbon D2 is renowned for excellent edge retention and abrasion resistance. SOG’s cryo treatment helps stabilize the steel’s microstructure for longer-lasting sharpness.
Black TiNi Coating
The Titanium Nitride finish adds corrosion and wear resistance while providing a low-glare, professional look that hides scratches better than bare steel.
Auto Deployment, Confident Lockup
A push-button automatic mechanism fires the blade fast and locks it open securely—ideal when one-handed operation matters.
Straight Back, Combo Edge Versatility
The reinforced straight-back profile excels at controlled push cuts; partial serrations rip through rope, webbing, and dense packaging.
Micro-Textured Aluminum Scales
Anodized aluminum keeps the weight down, the rigidity high, and the grip confident—especially with gloves or wet hands.
Carry-Ready Details
A pocket clip rides low for discreet carry (orientation may vary by run). Lanyard-friendly design provides additional retention options.

Performance You’ll Notice
Fast, One-Hand Access

Edge That Keeps Working
Cryo D2 shrugs off repeated cuts through cardboard, bands, and zip ties, reducing the frequency of touch-ups.

Serrations blast through fibrous materials; the plain edge delivers clean, controlled slicing and easy maintenance.
Durable, Low-Glare Finish
Black TiNi resists abrasion and corrosion and cuts reflections for a low-profile, professional aesthetic.

EDC & Work: Warehouse, facilities, and field jobs where a compact, tough cutter shines.
Outdoor & Travel Kits: Cord management, food prep (wipe clean), camp chores—pack-friendly size with real capability.
Care & Maintenance
After Use: Wipe the blade and add a light protective oil, especially after moisture or acidic foods.
Sharpening: Use diamond/ceramic stones on D2; maintain serrations with a tapered rod.
Mechanism Care: Keep the pivot and button channel clean and lightly lubricated; avoid heavy oils that attract grit.
Hardware Check: Periodically verify clip and body screws; a drop of blue thread locker keeps settings dialed.
