The SOG-TAC XR is the folding knife built for professional use — pulled into shape from feedback by the people who actually rely on a folder when conditions turn bad. 3.4 in. cryo-treated D2 clip-point blade, fully ambidextrous XR Lock, textured G10 handle that grips wet or gloved. Pick Blackout for the tactical/EDC blackout look (carbon-fiber-textured G10) or OD Green for the field/hunting look (machined G10 with a green tone).

Built for Hard Use

• XR Lock — SOG’s flagship lockup. Smooth, controlled one-handed opening with kick-open thumb stud or flipper; rock-steady lockup once deployed; ambidextrous release.
• Cryogenically-treated D2 blade steel — D2 is a tool-steel-grade workhorse with excellent edge retention; cryo treatment further refines the grain structure for better wear resistance and easier re-sharpening.
• 3.4 in. clip-point blade — versatile profile with a useful pointed tip and long cutting belly; flat grind for clean slicing through cord, webbing, tape, packaging, and game-dressing duty.
• Black coating on the blade — reduces glare, adds a corrosion-resistance layer over the D2; “STUDIES AND OBSERVATIONS GROUP” engraving honors the original SOG namesake unit.
• Textured G10 handle scales — composite material with deep texture for positive grip in rain, mud, cold, or with gloves on; checkered diamond pattern
• Fully ambidextrous controls — thumb stud, flipper, lock release, pocket clip all configurable for left- or right-hand carry
• Deep-carry pocket clip — black coated stainless, repositionable for tip-up carry on either side
• Lanyard hole at the butt of the handle for paracord or keychain
• 2-year SOG warranty against defects in materials and workmanship

Where It Shines

• Everyday carry where you want a serious tool — opening boxes, slicing cordage, trimming materials, kitchen-knife duty when you forgot to pack one
• Hunting camp — dressing small game, prepping kindling, cutting fishing line and lures, processing harvested birds
• Worksite utility — drywall scoring, strapping, tape, conduit prep, opening fertilizer or grass-seed sacks
• Tactical / professional duty — law enforcement secondary, EMS / fire utility, military EDC
• Gift for the hunter, contractor, first responder, or new homeowner who still uses a screwdriver to open boxes

Care & Maintenance

Cleaning: Wipe the blade dry after any wet use; for stubborn residue, mild soap and water then dry thoroughly. D2 has decent corrosion resistance for a tool steel but it’s NOT stainless — long contact with salt water or wet pockets will eventually rust the edge. The black blade coating adds protection; touch up any worn spots with light gun oil.

Pivot service: One drop of light machine oil at the pivot every few months keeps the XR Lock action smooth. Don’t over-tighten the pivot screw — just enough to remove side-to-side blade play.

Sharpening: D2 sharpens cleanly on a diamond stone or ceramic rod at ~20° per side. It takes a bit more passes than softer 420/440 steels but holds an edge much longer. A ceramic touch-up rod kept in the truck restores a working edge in 30 seconds.

Legal Note

Carry laws on folding knife blade lengths vary by state, county, and city. The 3.4 in. blade is street-legal in most U.S. jurisdictions but check your local statute before carry. Garoppo’s does not ship knives to jurisdictions where they’re restricted.
