SOG One-Zero XR – 3.10" Folding Knife, Plain Edge, Satin/Polished Cryo CPM S35VN Blade / Smoke Gray Sculpted Aluminum Handle
(Model SOG12730457 | UPC 729857014373)
Minimalist design meets maximum capability. The SOG One-Zero XR is a sleek, work-ready folder built around a premium 3.10" plain-edge blade of cryo-treated CPM S35VN and SOG’s ambidextrous XR Lock. A satin/polished finish highlights the clean geometry of the blade, while the smoke gray sculpted aluminum handle delivers lightweight strength, confident traction, and modern aesthetics that slide effortlessly from jobsite to office. If you want a compact everyday carry that’s refined in the pocket and relentless at the cut, the One-Zero XR (SOG12730457) is the move.
Why the One-Zero XR Stands Out
Premium CPM S35VN (Cryo-Treated)
Powder metallurgy S35VN balances edge retention, toughness, and corrosion resistance. Cryogenic treatment further stabilizes the steel’s microstructure for longer-lasting sharpness and durability.
Satin/Polished Blade Finish
A refined finish reduces drag through material and elevates the knife’s look—professional enough for desk duty, tough enough for daily utility.
XR Lock: Strong, Smooth, Ambidextrous
SOG’s XR Lock enables one-hand open/close from either side with secure lockup you can trust under hard use.
Sculpted Aluminum Scales
The smoke gray aluminum handle is lightweight yet rigid, with sculpted contours that improve grip while keeping the profile slim for pocket carry.
Carry-Ready Details
A pocket/belt clip rides discreetly; the handle design is lanyard-friendly for additional retention options.

Performance You’ll Notice
Cut Longer, Sharpen Less
S35VN (cryo) holds a keen edge through cardboard, zip ties, rope, and daily tasks—meaning fewer touch-ups and more productivity.
Secure, Confident Operation
The XR Lock offers smooth one-hand action with rock-solid lockup, so you can open and close safely even when your off-hand is busy.
Pocket-Friendly Strength
Aluminum scales keep weight down and rigidity up. The sculpted shape adds control without bulk for all-day comfort.
Ideal Use Cases
Everyday Carry (EDC): Package breakdowns, cable ties, plastic banding, light food prep.
Work/Shop: Utility cuts, scoring, trimming materials, and general maintenance.
Outdoor: Cordage management, fire prep (feathering), campsite chores.
Care & Maintenance
After Use: Wipe the blade clean; add a light protective oil if exposed to moisture or acidic materials.
Sharpening: Use diamond or ceramic stones; a small micro-bevel improves durability for tough media.
Hardware Check: Periodically verify pivot and clip screws; apply blue thread locker after final adjustments.
Frequently Asked Questions

Q: Plain edge vs. serrated?
A: The plain edge excels at clean, controlled slicing and is easier to maintain with a consistent edge angle.
Q: Can I use it for food prep?
A: Absolutely—just clean and dry the blade after cutting acidic or wet foods.
