Cold Steel Range Boss 4034SS Folding Knife - Olive Drab

EDC Folding Knife (Every Day Carry) equipped with a blade featuring a Clip-Point shape. Crafted from German 4034SS steel, the blade delivers outstanding corrosion resistance. A Stonewash finish provides a matte appearance, effectively reducing glare. Deployment of the blade is accomplished via a dual-sided thumb stud. Secure lockup is ensured by the Tri-Ad Lock mechanism. The handle, made from Zy-Ex composite in Olive Drab, offers a secure, non-slip grip. Daily carry convenience is enhanced by a spring clip.

German 4034SS steel

Forged from German stainless steel 4034SS, the blade offers excellent durability and superior resistance to corrosion. Under optimum heat treatment, the blade reaches a hardness between 54-57 HRC, delivering a resilient edge that is also easy to sharpen.

clip-point blade with stonewash finish

Equipped with a Clip-Point profile, the blade measures 101 mm in length and 3.5 mm in thickness. A plain cutting edge combined with a full flat grind ensures superior cutting efficiency and maintains the necessary strength for demanding use. Featuring a Stonewash finish, the blade offers a matte surface that not only minimizes glare but also enhances resistance to scratches.

handle made of glass-fiber reinforced nylon

Rugged Zy-Ex composite handle scales offer exceptional durability and a secure, non-slip grip in all conditions. Integrated finger grooves provide improved tool control, maintaining stability even when hands are wet or contaminated. Aggressive jimping along the handle spine offers a reliable thumb rest, enhancing precision and control during cutting tasks.

Reliable everyday carry is facilitated by a practical spring clip integrated into the handle, allowing the knife to be securely attached to a belt or pocket edge. The clip is fully reversible and can be positioned for optimal use by both right-handed and left-handed users.

tri-as lock, double-sided thumb stud

In the open position, the blade is secured by the Tri-Ad Lock system, an enhanced version of the traditional Back Lock, renowned for its exceptional stability and durability among folding knife locks. A double-sided stud mounted on the blade allows for quick, one-handed deployment using the thumb.

4034SS feature
4034SS
4034SS - an alternative designation for Krupp 4034 steel, also known as X46Cr13 or 1.4034, is a German martensitic stainless steel developed by ThyssenKrupp. The carbon content of 0.46% ensures moderate hardness, while chromium (13%) guarantees high resistance to corrosion and oxidation. The steel also has good hardenability and structural stability thanks to the addition of manganese (approx. 1%) and silicon (approx. 1%). After hardening, the steel achieves a hardness of 54-57 HRC, which ensures a durable but easy-to-resharpen edge. Thanks to its combination of corrosion resistance, easy maintenance, and good elasticity, 4034SS is a popular choice for the production of everyday carry (EDC) knives, hunting and kitchen knives, and tools.
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.
Zy-Ex feature
Zy-Ex
Zy-Ex is a composite material developed by Cold Steel, based on glass fiber reinforced polyamide. It is characterized by high mechanical strength, abrasion resistance, and low water absorption, allowing it to retain its properties even under intensive use in harsh conditions. The material is lightweight yet very rigid, allowing for the construction of a solid handle without excessively increasing the weight of the knife. The surface of Zy-Ex is designed to imitate the structure of natural wood, which gives it an attractive appearance and improves grip. Thanks to the combination of these features, Zy-Ex is used in tactical, outdoor, and EDC knives.

    With full conviction I give it 5 stars. A good price for Cold Steel. The lock holds solidly over time. The knife is very light, flat, and comfortable to carry. If someone likes full handles filling the hand, they should choose another. For me, carrying comfort is above comfort of momentary use. The clip is fully functional if you use fairly thin material, as usually found in tactical pants. If it's crucial to wear it clipped to jeans, you'll need to buy another clip, bend the existing one, or choose a different model. As for the handle texture – it's perfect. A 5-minute operation with sandpaper under the place the clip presses eliminates material wear.

    Cool little knife, a lot of blade at low weight, the lock gets loose pretty quickly, the clip holds very well, but the handle's texture is a misunderstanding – I haven't seen such a pocket-destroying grater in a long time. The knife itself is very flat and comfortable – steel is nothing special, but still has something to it.

    Great big knife, for me it is perfect for preparing meals outdoors thanks to the long blade and the stainless steel used, it works very well for this purpose. Of course, it is also suitable for other types of work.

    Large blade with a nice finish, the tri-ad click is pleasant to the ear and most importantly, right out of the box you can chop vegetables and fruit without any problem. I recommend it.

    A lot of sharpness for a reasonable price. Average build quality. Unfortunately, the clip serves only as a decoration. On the plus side, the Tri-ad Lock holds perfectly. Zero blade play, which is a positive surprise for such a thin handle.

    Very large blades in a slim form, a nice slicer for fruit or other food.

    A Broken Skull, but for less money ^^ It has a slightly thicker handle, which makes it fit better in the hand and allows for longer use without blisters.

    Despite having worse steel than the Air Lite, I actually liked it more, mainly due to the full flat grind.

    A nice, larger folder with a quite comfortable handle, but at this price I would expect better steel.
