Cold Steel AD-15 — 3.50" Folding Knife, Plain Spear Point, S35VN Stainless Steel Blade, Black Scales, Aluminum/G10 Handle
Model: CS58SQ • UPC: 705442018681
Built around Andrew Demko’s legendary Scorpion® Lock, the Cold Steel AD-15 is a hard-use folder that blends tank-like strength with EDC refinement. Its 3.50-inch spear-point, plain-edge blade is crafted from premium CPM S35VN stainless steel for excellent edge retention and corrosion resistance, while the black G10 scales over aluminum components deliver a secure, hand-filling grip without unnecessary weight. If you need a folding knife that inspires confidence on tough jobs and still carries comfortably, the AD-15 is your new benchmark.
Why the AD-15 Stands Out
Scorpion® Lock Strength: Demko’s unique yoke-and-spring lock clamps the blade tang from above, offering rock-solid lockup with outstanding resistance to shock and torque—perfect for real-world, high-load cutting.
Premium S35VN Blade: A modern powder metallurgy steel engineered for edge stability and toughness; easy to maintain a hair-popping working edge with routine touchups.
Balanced Spear-Point Geometry: Excellent tip strength and piercing control with enough belly for slicing rope, cardboard, strapping, and field tasks.
Grip That Won’t Quit: Textured black G10 scales over a robust aluminum frame provide confident traction in rain, sweat, or gloves.
Work-Ready Ergonomics: Deep finger guard, chamfered edges, and a neutral handle shape fit a wide range of hand sizes and grips.
Carry-Friendly: A thoughtful clip placement and slim profile ride neatly in the pocket while remaining ready for fast, secure deployment.

Real-World Performance
From warehouse pallets to campsite chores, the AD-15’s S35VN blade and rigid lock architecture shine when the cut gets demanding. The spear-point profile tracks straight in dense materials, while the tall flat grind offers excellent slicing efficiency without sacrificing tip strength. The Scorpion® Lock places your hand directly over the lock bar for intuitive pressure during hard cuts—resulting in outstanding control and confidence.
Ergonomics & Control
Secure Purchase: Aggressive but pocket-friendly G10 texture keeps the knife anchored in wet or gloved hands.
Hand-Filling Contours: Subtle palm swell and flared guard improve indexing and reduce hot spots over long sessions.
Ambidextrous Use: Dual thumb studs and reversible nature of the lock mechanism suit right- or left-handed users (clip orientation varies by run).
Built to Carry Every Day
Despite its brute strength, the AD-15 remains an EDC-viable package. The pocket clip positions the knife for quick access without printing, and the overall thickness feels substantial in hand yet disappears in pants, work shorts, or a pack organizer.
Ideal Use Cases
Work & Trades: Break down heavy cardboard, trim banding, notch hose, and slice nylon straps.
Outdoor & Field: Camp meal prep, cordage management, stake shaping, and general utility.
Preparedness & Travel Kits: A premium steel blade in a format you’ll actually carry daily.
Care & Maintenance
Wipe & Dry: After use—particularly after acidic foods or wet conditions—wipe the blade clean and dry.
Edge Touchups: Maintain with ceramic rods or fine diamond stones; S35VN responds well to light, frequent maintenance.
Pivot & Lock: Add a drop of quality oil to the pivot when needed; keep the Scorpion® Lock channel free of grit for smooth operation.
Hardware Check: Periodically inspect pocket-clip screws and body hardware for snugness.
Frequently Asked Questions
Q: How strong is the Scorpion® Lock compared to liner or frame locks?
A: It’s engineered for exceptional strength and shock resistance. The lock’s top-down clamping action and hand-over-lock ergonomics distribute force in a way traditional side-engagement locks typically don’t.
Q: Is the edge serrated?
A: No. This model features a plain edge for clean, controllable cuts and easier sharpening in the field.
Q: Can I use it for food prep?
A: Absolutely—S35VN offers excellent corrosion resistance. Clean and dry afterward for best long-term performance.
Q: Is the clip reversible?
A: Many runs allow reversible tip-up carry; confirm the included hardware with your specific unit.
