SOG SEAL XR – 3.90" Folding Knife, Clip Point, Partially Serrated, Black Cerakote® S35VN Blade / Black GRN Handle, Belt Clip
(Model SOG12210557 | UPC 729857013666)
When the job demands a hard-use folder with mission-grade materials, reach for the SOG SEAL XR (partially serrated). Built around a near full-size 3.90" clip-point blade of premium CPM S35VN stainless steel, this SEAL-line folder adds a versatile combo edge that chews through rope, webbing, and fibrous materials while leaving a long, clean plain edge for precision cuts. A durable, non-reflective Black Cerakote® shields the blade from corrosion and abrasion, while the ambidextrous XR Lock delivers rock-solid lockup and confident one-hand operation. The black GRN (glass-reinforced nylon) handle offers aggressive texture with comfortable contours, and the included belt/pocket clip keeps the knife secure and ready.
From duty and rescue to field craft and everyday tasks, the SEAL XR SOG12210557 is a purpose-built folding knife that performs when everything is on the line.
Why the SEAL XR Combo Edge Stands Out
Premium CPM S35VN Blade Steel
Powder-metallurgy S35VN balances edge retention, toughness, and corrosion resistance—ideal for a heavy-rotation EDC or professional tool.
Partially Serrated Clip-Point
The combo edge pairs slicing efficiency with serration bite for fast work through nylon straps, line, seatbelts, and cardboard—while keeping a long plain edge for clean, controlled cuts.
Black Cerakote® Protection
Rugged ceramic coating reduces glare and adds abrasion and corrosion resistance for harsh, wet, or salty environments.
XR Lock Strength & Speed
The XR Lock enables ambidextrous one-hand open/close with outstanding lock strength you can trust during aggressive cuts.
All-Weather GRN Handle
Black GRN scales with molded traction keep weight down and grip secure—gloved or bare hands, rain or sweat.
Carry-Ready Design
A belt/pocket clip rides secure and discreet; the handle is lanyard-friendly for additional retention options.

Performance You’ll Notice
Cut Longer, Sharpen Less
S35VN’s fine carbide structure offers excellent edge stability, so the plain edge stays keen and the serrations keep biting through tough media.
Confident, One-Handed Control
With the XR Lock, you get a strong, repeatable lockup and smooth, ambidextrous operation—open and close with authority, even in gloves.
Low-Glare, High-Durability Blade
Black Cerakote® minimizes reflection and stands up to daily abrasion, moisture, and grime.
Ideal Use Cases
First Responders & Duty – Rapid strap/seatbelt cuts, cordage management, utility tasks with a secure lock and tough steel.
Outdoor & Field – Food prep, paracord, shelter line, and light wood tasks; serrations excel in wet, dirty conditions.
Everyday Carry – Warehouse, jobsite, or around the house—break down boxes, slice packing straps, and tackle general EDC chores.
Care & Maintenance
After Use: Wipe blade and pivot; add a light coat of oil (especially after wet or acidic exposure).
Sharpening: Use diamond/ceramic stones for S35VN; refresh the plain edge with a micro-bevel. Clean serrations with a tapered/rod sharpener that matches the gullets.
Hardware: Periodically check pivot and clip screws; apply a tiny drop of thread locker if needed.
Frequently Asked Questions
Q: What advantages do serrations add?
A: Serrations grip and saw through fibrous materials quickly, especially when wet or dirty, while the plain edge handles precision slicing.
Q: Is the XR Lock left-hand friendly?
A: Yes. The XR Lock is fully ambidextrous, enabling one-hand open/close for right- or left-handed users.
Q: How tough is Cerakote?
A: Cerakote® is a proven ceramic coating that boosts wear and corrosion resistance and cuts glare—ideal for duty and outdoor use.
Q: Will S35VN rust?
A: It’s a stainless tool steel with strong corrosion resistance. Still, wipe dry and oil lightly for best long-term performance.
