SOG One-Zero XR – 3.10" Folding Knife, Plain Edge, Black Chrome (Cryo CPM S35VN) Blade / White Sculpted Aluminum Handle
(Model SOG12730557 | UPC 729857014380)
Modern minimalism meets mission-ready performance. The SOG One-Zero XR pairs a compact 3.10" plain-edge blade of cryo-treated CPM S35VN with a striking Black Chrome finish and SOG’s ambidextrous XR Lock. The result is a fast, secure, and premium everyday carry that looks at home in the office yet works like a shop tool. The white sculpted aluminum handle keeps weight low, adds rigidity and grip-enhancing contours, and delivers a clean, monochrome aesthetic that stands out without shouting.
If you want a sleek EDC that blends top-tier steel, a rock-solid lock, and refined ergonomics, the One-Zero XR (SOG12730557) is built for your pocket.
Why the One-Zero XR Stands Out
Premium CPM S35VN (Cryo-Treated) Blade
Powder metallurgy S35VN is engineered for excellent edge retention, toughness, and corrosion resistance. A cryogenic treatment further stabilizes the matrix for longer-lasting sharpness and edge stability under hard use.
Black Chrome Blade Finish
The low-glare Black Chrome treatment adds abrasion and corrosion resistance while giving the blade a sophisticated, stealthy look that resists fingerprints and everyday scuffs.
XR Lock – Strong, Smooth, Ambidextrous
SOG’s XR Lock allows confident one-hand open/close for left- or right-hand users and delivers secure, repeatable lockup you can trust.
White Sculpted Aluminum Scales
Lightweight aluminum is milled with subtle contours for grip and control while maintaining a slim, pocket-friendly profile and distinctive white finish.
Carry-Ready, Everywhere
A discreet pocket/belt clip (orientation may vary by run) and lanyard-friendly design round out a package that disappears in pocket yet deploys instantly.

Performance You’ll Notice
Cut Longer, Sharpen Less
Cryo CPM S35VN keeps a keen edge through cardboard, nylon strap, zip ties, and daily utility tasks—reducing maintenance and boosting productivity.
Confident Control in Any Grip
The sculpted aluminum handle enhances indexing and control without adding bulk, while the XR Lock keeps the blade securely open until you’re ready to close it—with one hand.
Low-Glare Durability
Black Chrome helps the blade shrug off wear and corrosion and keeps reflections to a minimum—ideal for professional and field settings.
Ideal Use Cases
Everyday Carry (EDC): Box breakdowns, packaging, light food prep, cordage management.
Work & Shop: Scoring, trimming, precision slicing on the jobsite or bench.
Outdoor & Travel: Camp chores, kit duty, and on-the-go utility in a lightweight package.
Care & Maintenance
After Use: Wipe the blade clean; add a light protective oil after moisture or acidic foods.
Sharpening: Use diamond or ceramic stones; a small micro-bevel strengthens the edge for tough media.
Hardware Check: Periodically verify pivot and clip screws; apply blue thread locker once dialed.
Handle Care: Clean the white aluminum scales with mild soap and water; avoid harsh abrasives to preserve the finish.
