Cold Steel 4-Max Scout AUS-10A Folding Knife

Everyday carry (EDC) folding knife crafted by American knifemaker Andrew Demko. The blade is constructed from Japanese AUS-10A steel, which is highly resistant to corrosion. A Stonewash finish delivers a matte look, minimizing unwanted reflections. The black handle, made from Griv-Ex composite, ensures a secure, non-slip hold. Quick deployment is made possible with a double-sided thumb stud, while a Tri-Ad Lock mechanism reliably secures the blade during operation.

Japanese stainless steel AUS-10A

Forged from Japanese AUS-10A steel, the blade delivers outstanding strength along with superior resistance to corrosion and wear. Upon hardening, it reaches a hardness level of 58-61 HRC.

Drop-Point blade profile, stonewash finish

Featuring a Drop-Point blade profile, the knife offers a 101 mm long blade with a 4.8 mm thickness. A high flat grind is used to craft the smooth cutting edge, enhancing performance. The use of the Stonewash method for the blade finish delivers a matte surface that reduces glare and efficiently conceals the signs of regular wear. The blade's shape delivers outstanding cutting capabilities while providing ample durability, making it suitable for demanding tasks.

Ergonomic Griv-Ex composite handle, steel clip

A stainless steel framework forms the foundation of the handle, complemented by scales and a back spacer crafted from rugged Griv-Ex composite. The handle features a non-slip texture that ensures a secure grip even in wet or dirty conditions, while the finger grooves enhance overall tool control. The handle's large, ergonomically contoured design offers comfort whether used barehanded or with gloves. A dedicated hole at the end of the handle allows for lanyard attachment.

A tip-up steel clip comes mounted to the knife and is reversible for both sides of the handle, making it suitable for both right- and left-handed operation.

Tri-Ad Lock, double-sided stud

With the blade open, the Tri-Ad Lock system ensures secure locking. As an enhanced evolution of the traditional Back Lock, it is recognized as one of the most durable locking mechanisms found on folding knives. Its design incorporates a stop pin that absorbs forces exerted on the blade, channeling them into the handle to significantly reduce wear on the mechanism. By automatically adapting to normal use, the system preserves lock integrity and dependability over time. A double-sided thumb stud mounted on the blade enables fast, ambidextrous one-handed deployment.

AUS-10 feature
AUS-10
AUS-10 is a high-quality stainless steel produced by the Japanese company Aichi Steel, considered one of the best in the AUS steel series, used mainly in mid-range and high-end utility knives, produced mainly in Japan and Taiwan. The carbon content (0.95-1.1%) ensures high hardness, while chromium (13-14.5%) guarantees very good corrosion and abrasion resistance. The steel also contains manganese (up to 1%), silicon (up to 1%), phosphorus (up to 0.025%), and sulfur (up to 0.025%), which affect hardenability, impact strength, elasticity, and machinability, improving structural stability and maintaining mechanical properties. After hardening, the steel achieves a hardness of 58-61 HRC, offering an excellent balance between strength, edge retention, and ease of sharpening. It is comparable to 440C steel, differing in carbon content and the addition of vanadium, which improves structural homogeneity and increases abrasion resistance.
Tri-Ad Lock feature
Tri-Ad Lock
Tri-Ad Lock is a lock developed by Cold Steel and Andrew Demko, considered one of the strongest systems in folding knives. Its key element is a stop pin, which takes the pressure from the blade and distributes it to the handle, protecting the lock from wear and overload. The mechanism is designed to self-adjust over time, which maintains the reliability of the lock even after prolonged use. In tests, it has proven resistant to loads of up to hundreds of pounds, confirming its durability.
Stonewash feature
Stonewash
Stonewash is a blade finishing technique that involves treating steel in a drum filled with stones, ceramic abrasives, or beads. The impact of the material creates a characteristic, irregular pattern with micro-scratches, giving the effect of a matte, slightly “aged” surface with a raw, practical appearance. The finish gives the knife an aesthetic look and masks minor scratches and marks that occur during use, keeping the blade looking like new for longer. The matte texture reduces light reflections, which is valued in tactical and outdoor knives, and the micro-scratches can further reduce friction during cutting. Due to its durability, discreet appearance, and ease of maintenance, stonewash is popular in EDC, field, and tactical knives.
Griv-Ex feature
Griv-Ex
Griv-Ex is a durable glass-nylon composite reinforced with fiberglass used by Cold Steel, mainly for the production of knife handles, and in some models also for blade components. The material has a textured surface on the handles, which ensures a secure, non-slip grip, and its maintenance usually boils down to simple washing under running water. Griv-Ex is distinguished by its resistance to moisture, corrosion, mechanical damage, and extreme temperatures, and does not warp or crack under harsh conditions. When used in the construction of blades, it is additionally stabilized by UV rays and heat, which further increases its durability.

    Knife 100% matches the description and photos, can actually replace a small fixed-blade knife. When held by the end of the handle, it chops quite well, and in the forest, it's good for more than just mushrooms.

    Very well-made piece of a good knife. Thanks to the folding function, you can take it anywhere. Sharp and handy. I definitely recommend it.

    It's heavy and costs a bit, but I would buy it again without hesitation, a real battleship, amazing looks, and the triadlock could lock up large-caliber firearms.

    First impression after grabbing it: what a BRUTE! A folding cleaver, but it cuts surprisingly well for such a thick blade, because the bevel is high and CS sharpens well. It has POWER, I recommend it!

    A piece of a tank-like knife, and a beautiful classic design by Andrew Demko. Great alternative to the "elite" version of this knife, because for a quarter of the price you get the same durability and ergonomics, just with less "premium" materials. I've been carrying and using it since March, at first you can feel it's a "brick," but the sense of solidity and safety makes up for it. Knife for a grill and World War III alike, the look alone will scare off anyone ;)

    3-in-1 pocket knife – small machete, a hatchet for light chopping, and a knife for preparing food. Recommended if you want to carry one thing instead of three in your backpack. Very sharp out of the box.

    Very solid knife, well-sharpened out of the box, for heavy outdoor work. The clip, as always with CS, is shallow and destroys the pocket, but I still recommend it.

    A real chunk of a knife, a folding opener for tank hatches. Great quality, tank-like lock. Chops thick branches, batons, and nothing happens to it.

    Power with a capital P, just excellent. Be careful with your fingers when closing, very sharp.

    A true pocket cleaver! Highly recommended!

    An explosive knife, heavy, a solid piece of a tank hatch opener.

    For its dimensions, the pocket knife is very comfortable to use, very sharp out of the box. Excellent for cooking in the forest, spreading butter, slicing meat. Size comparison is shown in the photo with code 4.

    Powerful, well-made knife

    Powerful, heavy, solid. Surprising sharpness for such a thick blade. Fresh stick 1 cm thick cut in a single short motion, no sawing, almost no effort. Handle has a lot of space, comfortable, grip a bit too rough for my taste. Be careful when closing, easy to pinch your fingers – my method is to hold it at about a 45-degree angle downward, release the lock and close it against my thigh (of course, safest to use both hands). There is a comparison photo with LAND 910.

    Blade play within the norm, lock is reliable, steel is decent. The size really impresses. Sharpened to shave a mustache. I recommend it.
