OTF Double Action Knife Summary

If you are new to OTF knives, then I recommend you take a look at the guide below.

Learn More About OTF Knives?

In this section, you will learn everything you need about OTF knives to make an informed decision. You will learn what OTF stands for and what is meant when referring to a “dual action” knife. You will also become more familiar about their weight, the type of material used to make the blade and also what the glass breaker is used for. Happy learning.

What is an OTF knife?

OTF stands for Out-The-Front and is a unique feature where the blade slides out of the hole in one end of the handle. It is important to note that it is not a folding knife because the blade slides out in a parallel fashion.

The blade portion will rest inside the handle and tension will be built up with the help of small spring located inside the handle. There is a switch on the handle that when pressed will release the pressure and allow the blade to deploy. Above is a video that will demonstrate how an OTF knife works.

What about dual action?

Most OTF knives are also single action which means the switch will only automatically deploy the blade while you need to press the blade into the handle to retract it manually. When an OTF blade is dual action, it merely means that the blade will automatically eject once the stitch is pressed forward and will also automatically retract once the button or switch is pulled back. You do not need to touch the blade to get it back inside the handle.

More on the weight of these blades

Almost all of the blades in this category are small, compact and do not weight much. The weight can range from 3.35 oz up to 15.2 oz. The heaviest knife in this selection has a weight that is also insignificant. The lightest knife is this one from MTN while the heavies ones are the Venom 2R and the Venom 3R.

The type of material used

The knives in this section make use of only three types of steel which include the 440c, 4034 and the D2 steel. The 4034 steel is the weakest of the three and also the cheapest.

  • 440c Steel: This type of steel is a 440 stainless steel that has the highest carbon content in the series. It is tough and mostly used in bearings and to make blades. It is a very tough steel that can handle a lot of pressure and wear resistance. This type of steel and provides the sharpest edges for knives and is ideal for knife making.
  • 4034 Stainless Steel: This type of steel is softer than that of the 440 types. This steel is not brittle, but will not stay sharp for very long and will need to be sharpened at a consistent basis. This steel is also very inexpensive.
  • D2 Steel: This steel is high in carbon and chromium which makes it very hard and tough steel. This steel is not meant to make very fine edges and works better on robust edges. It is also tough to sharpen. This type of steel is best used for hunting and tactical knives.

All of them have a glass breaker

It is hard to not associate a glass breaker at the other end of tactical knives. Some tactical pens also make use of a glass breaker. A glass breaker is a sharp point on the back of the handle which is mainly made out of tungsten steel or any other hard steel. The sharp point is used to break the glass.

In which situation would you use this tool? If you are stuck in a burning car or inside a vehicle while underwater, then this sharp and handy tool might be your only option for escaping the car. It is straightforward to use as you only need to strike one of the windows with it. It can also be turned into a deadly weapon used to defend yourself.

Any extras?

Some of the knives in this section also include some additional items. For instance, this knife from MTN comes with a small 500-lumen tactical flashlight and a multipurpose tool. Almost all of the other knives come with a pouch in which to carry it. Some blades will also have a belt clip at the side of the handle that can be used to attach the knife to your belt.
