Out the Front (OTF) knives have become pretty popular in the last decade. Because of this, I decided to try one out. Cobratec Knives offered me one of their Large Black Mamba’s to review. This is one of their cost effective automatic OTF knives. As it uses D2 for the blade steel. Also, do not let the name fool you, large does not mean huge. The Large Black Mamba is a good size Every Day Carry (EDC) knife.

As stated, the Cobratec Large Black Mamba is an OTF knife. If you are new to knives, that means the blade actually extends out the front of the knife, through a slot in the end of the handle, automatically. It does this by either a button or switch located somewhere on the handle. The Black Mamba uses a slider switch on the top edge of the handle. It is a dual action switch. Slide it forward to extend the knife’s blade out, and rearward to retract the blade. I do like the switch on the Black Mamba. It has some serrations on it to let your thumb get a good grip on it. The switch is also ramped up and down to position your thumb at the perfect location to use said switch.

The specifications of the Black Mamba are what make it a good OTF knife. Even though Cobratec calls it the “Large” Black Mamba, it’s only called large because it is the biggest in the Mamba line. The blade’s length is 3.25 inches long. Making it the same size as a ton of folding EDC knives on the market. Moving to the handle, it has a length of 4.75 inches. This makes sense to me, since the handle houses the mechanism to open the knife, as well as the blade itself. That makes the total length, opened, to be 8.25 inches. The handle's thickness comes in at 0.49 inches and 0.60 with the pocket clip. The height of the handle measures 0.925 inches wide or 1.09 inches if you include the slider switch. I thought the Black Mamba would be larger, but once I received it, I realized it’s basically the same size as most of my EDC knives.

Cobratec uses D2 steel for the Large Black Mamba’s blade. I like D2 as I believe it is one of the best lesser expensive steels used in knife blades. This also helps keep the cost of this OTF knife down. D2 is not a stainless steel, so to help keep it from the elements, Cobratec gave it a black titanium coating. The coating does two things: It helps protect the blade and it gives it a really nice look. The blade on the Black Mamba is a drop point shape. It is also not serrated. I’m okay with this as I find straight drop point blades very functional. This particular blade is 0.100 inch thick and 0.650 wide. I would have possibly liked a wider blade, but I am not a OTF designer. So there are probably design limitations due to the handle’s width. But the Black Mamba’s blade shape worked well. Being that the Black Mamba is an OTF automatic knife, it does have a blade safety mechanism. If you try to open the knife with something significant blocking the blade from pushing out, the blade will release from the opening mechanism and become loose inside the handle. It will also disengage if you hold the blade tight while trying to retract the blade back into the knife. To get the Black Mamba back into action, just pull the blade all the way out and it will re-engage the opening/closing mechanism. You can also flick the knife and use gravity to do the same thing. This is a common safety feature on OTF knives.

I mentioned the handle’s dimensions, but let’s go a little deeper into the handle. The Black Mamba’s handle has little squares machined into it for grip texture. Actually, the lines are machined in it to make the squares. On the top and bottom, Cobratec machined some lines in to give rectangles. All of these squares and rectangles give the Black Mamba a really good grip. Especially since the handle is made from 6061 aluminum, and aluminum can be slick. On the rear of the handle is a built-in glass breaker, should you ever need one. Also on the handle is the pocket clip. It is tip down, right hand only. Tip down is because it is an auto knife. When you grab the knife out of your pocket, your hand is already positioned with the pokey end pointed away from you. So when you push the opener switch, you don’t get hurt. My only real complaint about the Black Mamba is its pocket clip, it is not a deep carry clip. However, the pocket clip works extremely well and is very strong.

As with almost all of my knife reviews, I like to actually use the knife. I carried the Large Black Mamba for a while. It carries really well. Or at least as good as most of my flipper style knives. The D2 blade came extremely sharp from the factory. I have had to touch it up twice. D2 sharpens pretty easily, so it wasn’t a big deal. One of those times I dulled it up by scraping some stuff off of a metal surface. Probably something that no knife maker recommends. The opening mechanism has also never let me down. Plus it is super easy and fast to use. I’m not a big OTF guy, but the Black Mamba performed great for everything I threw its way.

If you like OTF knives, or maybe want to get into OTF knives, the Large Black Mamba might be just what you are looking for. It is priced right at $170. Has a good blade steel. It functions fantastic and has a good blade shape. What more could you want from an OTF knife? Go check out the Cobratec Large Black Mamba and see for yourself. Or at least take a look into all the other OTF knives Cobratec makes.

Here we have, for review, The Black Raptor Dagger from CobraTec. A knife company that I have just absolutely fallen in love with. The company, as you can see, is CobraTec. On the Gun & Gear Review podcast we discussed one of their knives, and before the show even started I bought the knife and had it on the way to me. That particular knife is the Trapper model with the hidden open switch. Since then I have ordered and paid for 3 more of their knives, plus I have given a few away as door prizes and gifts to friends. Some went to Tony Simon over at his Diversity Shoot. So needless to say, I have been digging these knives pretty well. The knife review today was sent to me by CobraTec, after I reached out to them. They were more than happy to send me this Black Raptor dagger.

So what we have here is a knife that is an OTF (out the front) knife, it has a side fire switch made out of aluminum with nice knurling on it to get a good thumb purchase. The handles or case of the knife is CNC machined 6061-T6 aluminum. This is what a lot of firearms and lower receivers are made out of. The blade of the knife is D2 tool steel and is a dagger point that is sharpened on both sides and is very sharp from the factory. The action of this knife is smooth and the lock up is nice and tight. I have used more expensive OTF knives that have rattled once the blades were deployed, but not this one.

Here are the factory specs on the knife and then I will get into some more details of what I like and maybe what I don't.

Specifications:

Weight: 3 oz
Overall Length: 7.63"
Blade Length: 3.13"
Handle Length: 4.5"
Blade Material: D2 Steel Blade
Aluminum Switch

Most everyone knows that I love D2 tool steel, it is an amazing steel for blades. It is not the sharpest steel out, the most expensive, but in my opinion it is one of the best all around steels for durability, ease of taking care of, sharpening and longevity of a blade. I think they did a fantastic job of picking this steel for their knives.

CobraTec Is an American company based in Meridian, Texas, they have their blades manufactured overseas to meet their specifications. Then once they are imported back to Texas, a group of technicians assemble the knives and do a quality control on them. This ensures that the end user is getting a quality built, reliable knife with a lifetime warranty. All of the blades are sent out to a metallurgical research laboratory for testing. Now that is quality control right there people.

The Raptor came packaged in a great hard plastic case with a foam insert that held the knife in place. It also had a card with the person who assembled and inspected the knife. There was also a warranty card in the box as well. All you have to do is follow the directions and go to the website and put the code in. Your knife will be warrantied to you for a lifetime.

With the Raptor being a dagger style blade I did not get to do my usual type of skinning or typical EDC fingernail cleaning with it. What I can tell you is that it is sharp. It will puncture through just about any normal thing you want to stab with it, within reason. I did sharpen the D2 blades on both sides, I didn't have to but I did, it was already sharp enough.

One good thing about their OTF knives is that you can order different style blades for them at a reasonable price. They have tanto, drop point, and the dagger style. This blade style is not one I myself like, because I like a blade that I can use to work with everyday. My opinion on this doesn't take away from what the knife was intended for. This is a defensive knife and a damn good one at that. So if you're looking for a EDC OTF knife for self defense look at the CobraTec Raptor, it will not disappoint at all. CobraTec also has many options, styles and price points for everyone.
