If you’re looking for a one-handed carry knife, an OTF (out the front) design is ideal. With a spring assisted open and close action, they’re perfect for everyday use.
OTF knives are often made from stainless steel. Stainless steel is highly durable and will hold up to heavy-duty use. Stainless steel blades are also typically sharper than a standard carbon steel knife.
Blade Length
OTF (out the front) knives have blades that are automatically deployed via a switch. This is different from spring-assisted and gravity knives which require the user to pull the main blade in and release it with a button or mechanism before deploying the blade.
The blade length is measured from the tang, which extends from where the blade attaches to the handle, to the sharpened edge. This is a standard method of measuring the blade length and should be used in all product descriptions.
An OTF knife is considered a switchblade knife in Vermont and is illegal to carry in public, sell or transfer. In order to determine whether a knife is a switchblade, law enforcement must perform a two-part test: does the knife primarily “attack or defend” humans and is it a restricted weapon?
Blade Shape
OTF knives, or out the front knives, are automatic knives that deploy straight from the handle. They are one of the most popular switchblades on the market and have a distinct menacing aesthetic.
Otf knives are available in a variety of blade shapes and sizes. Some are designed specifically for self-defense, while others are for everyday utility use.
Most OTF knives are made out of stainless steel or carbon steel. These materials are rust-resistant and durable, so they will last for years.
Blade Edge
When it comes to knives, the blade edge is one of the most important features. It determines how well the knife cuts, and whether it will chip or roll over.
A good blade edge is made from a fine-grained, hard steel that resists the formation of cracks and chips. It also is less prone to dulling because it has a crystalline structure without “buffers” between the different grains of metal that can cause the blade edge to deform and lose its sharpness.
The edge of the blade is a crucial part of the strength and slicing ability of an otf knife, so understanding how to measure it is essential. Using the proper measuring method ensures that you get a blade that is perfect for you and your needs.
Handle Length
The handle length is an important measure to consider when making an otf knife. It helps to ensure that your blade is the right size for your hand.
The length of a handle is measured by measuring it from the shortest point to the tallest. Generally, handles are between 0.75″ and 1″ at the shortest and 1.25″ to 1.5″ at the tallest.
The handle on your otf knife should be large enough to house the tang of the blade without becoming structurally weak or feeling too bulky. It should also be long enough to provide a secure grip while providing room for your fingers to close around the tip of the blade.
Weight
OTF knives (Out the Front Knives) are automatic knives that deploy a blade with one hand and at the press of a button. They are primarily used by law enforcement and military operators.
They are also a good option for first responders who need to manipulate rescue gear or cut away a seatbelt in an emergency situation. However, they are not legal for civilian use.
The main weakness of OTFs is that the spring doesn’t have enough power to fully extend the blade, so it will often stick a little bit open. Fortunately, it’s only a small amount, but it can still be dangerous to unwitting victims.
