Cold Steel SRK SK5 Fixed Blade Knife - OD Green

Robust tactical-knife design featuring Full Length Tang construction, merging the performance of a survival, combat, and rescue knife. Outfitted with a Clip-Point blade crafted from high-carbon SK-5 steel for outstanding strength and excellent edge retention. The blade sports a black, matte Tuff-Ex finish for added protection. The handle, presented in Desert Tan, is constructed from Kray‑Ex material and features a non-slip surface for a secure grip. Supplied with a sheath equipped with a Secure‑Ex system, enabling convenient belt carry or attachment to various gear.

The SRK model enjoys recognition from both the military and law enforcement, and is issued to Navy SEALs for use during BUDS (Basic Underwater Demolition Training).

SK-5 tool steel resistant to cracking

Forged from SK-5 tool steel, the blade offers exceptional durability and is highly resistant to cracking, chipping, and dulling. The blade is also easy to sharpen. Once hardened, it reaches a hardness of 63-65 HRC, delivering impressive wear resistance and outstanding durability.

Clip-Point blade coated with Tuff-Ex

Equipped with a Clip-Point profile, the smooth-edged blade measures 152 mm in length and 5 mm in thickness. Featuring a hollow grind, the blade delivers efficient slicing and high precision for various tasks. Protected by a black, matte Tuff-Ex finish, the surface prevents reflections and offers strong corrosion resistance. A shortened ricasso brings the cutting edge forward, providing an extended cutting surface.

Handle with Kray-Ex, Full Length Tang construction

The handle is crafted from Kray-Ex material with pronounced texturing, ensuring a reliable grip even when hands are wet or dirty. Designed with a Full Length Tang construction, the blade’s tang extends throughout the handle, remaining only slightly narrower at the end. A cross guard is integrated to prevent fingers from sliding onto the blade. At the end of the handle, a hole is provided for the attachment of a lanyard or strap.

Sheath with Secure-Ex system, multi-position mounting capability

The supplied sheath is crafted using the Secure-Ex system from a material that is lightweight, highly durable, and resistant to weather conditions. A precision-molded inlet combined with a snap-fastened loop ensures the knife remains securely in place, effectively preventing accidental drops. The loop facilitates easy attachment to a belt, while multiple holes and grommets offer versatile multi-position mounting options for belts or various gear components.

features and technologies

Tuff-Ex

Tuff-Ex is a protective coating developed by Cold Steel, applied to knife blades to increase their durability and functionality. It gives a matte black finish and eliminates glare, which is important in tactical and survival applications. The coating effectively protects the steel from corrosion and other surface damage, extending the life of the tool. Tuff-Ex is highly abrasion resistant and retains its protective properties under heavy use. The coating is used on popular Cold Steel knife models such as the SRK and Recon Tanto, which are made of SK-5 steel.

Secure-Ex

Secure-Ex is a system developed by Cold Steel, designed for the safe storage and convenient carrying of knives and tools. Sheaths made with this technology are lightweight, durable, and weather-resistant, making them suitable even for intensive use. They hold the knife securely in the sheath while allowing for quick and smooth draw. The system has a modular design - the sheaths can be supplemented with various fasteners, such as buckles, clips (e.g., C-Clip) or ball chains. This allows the knife to be worn on a belt, around the neck, or in other configurations, according to the user's preferences.

Kray-Ex

Kray-Ex is a synthetic polymer with a rubber-like structure used by Cold Steel to manufacture knife handles. It is characterized by high adhesion and anti-slip properties, ensuring a secure grip even in high humidity, low temperatures, and with dirty hands. The material is flexible and absorbs shocks well, which increases comfort of use. Kray-Ex is also resistant to cracking, abrasion, chemicals, and adverse weather conditions, making handles made of this material durable and virtually maintenance-free. Cold Steel uses it in tactical, survival, and utility knives.

SK-5

SK-5 steel belongs to a series of Japanese tool steel (Steel Kuogu) with high carbon content and good wear resistance. It is equivalent to American 1080 steel and is also designated as SK-85. It contains about 0.8-0.9% carbon, which gives it high hardness and very good cutting properties. The addition of manganese (0.1-0.5%) improves hardenability, silicon (0.1-0.35%) increases elasticity and strength, and small amounts of chromium (about 0.3%) and copper (up to 0.025%) promote the steel's wear resistance and slow down degradation processes. The presence of nickel (up to 0.25%) further enhances strength, while low sulfur and phosphorus content reduces the material's brittleness. After quenching, SK-5 reaches a hardness of up to 63-65 HRC, and its martensitic structure with fine carbides provides a favorable combination of wear resistance and mechanical strength. Thanks to these properties, the steel is used in chisels, saws, springs, drills, and in utility and tactical knives.

Review for model:

The sharpness holds up decently. Admittedly, after a while of use, it’s no longer a "razor blade," so it won’t cut paper or shave hair, but it still cuts wood very well all the time. So far, I’ve only tested it once during a May weekend. It sliced meat and potatoes, split wood, nothing broke, and it didn’t become overly dull. Only the coating on the blade comes off almost immediately (as you can see in the photos), so it seems to be more decorative than real protection, but aside from that, it works great. If any flaws, problems, or defects appear after longer use, I’ll update the review, although I’ve been using another knife from this manufacturer for about six years now and it’s still perfectly fine.

Review for model:

Overall, a solid piece of flat bar for the job. In my opinion, a fairly significant downside is the rubber handle. It's easy to damage, for example during batoning, which happened to me. Hard handles work much better for me (like micarta in Za-pas knives). Overall, it's okay, but I wouldn't buy it again.

A excellently crafted knife, the handle 'sticks to the hand', and the length of the knife is perfect. Very sharp and comfortable to use. The sheath has no complaints. Bought on promotion, worth its price.

Review for model:

The purchased SRK SK-5 knife does not have a blade with a thickness of 5 mm, but only 4.3 mm at the thickest visible point, that is, right next to the handle. On the box and in the store's description, a thickness of 5 mm is given. I have a good caliper and I know how to use it. Whether the blade steel of this knife is indeed SK-5 steel—I am unable to verify. As for the blade thickness, the received product does not match the store description.

Review for model:

I don't understand the hype about this knife? Besides looking good, it's not a knife you can rely on in the field. During batoning, the blade broke at the handle. It was replaced under warranty and I was sent a new one. The next one, after a short period of use, developed play in the handle. This is a big discomfort when working with the knife, as I don't know if it will completely come out, and we all know how that can end. Besides the fact that it keeps its sharpness well, I wouldn't trade it for my Chinese knife, which cost 60 PLN and is indestructible.

I recommend the Cold Steel SRK to everyone. Solid steel, the handle fits perfectly in the hand. The whole thing is solidly made, and when unpacking I noticed the blade was lubricated with oil, which isn't standard. I should add it's incredibly sharp.

An outstanding knife. It has a large size, but if someone has a bigger hand, it will be perfect. Rugged and simple. Very convenient to use. The fact that it comes coated with a thick layer of preservative speaks of its quality. An ideal choice when it comes to versatility.
