How does switchblade knife work

Out-of-the-front knives as the name suggests fire open only through the front. These knives can be used across all domains of everyday life, for personal or professional use.

They are ideal as they can be operated single-handedly and be savvy time-savers. How do OTF knives work? Just like all other EDC knives exception for fixed blade knives the blade is concealed within the handle.

Contrary to folding knives which are operated manually, OTF knives are automatic and when activated the blade springs open through the front and locks into place. There is usually a button or slide switch that activates the internal mechanism to allow the blade to eject. OTF knives can either be operated by a single-action or double-action mechanism. These knives have a release button that ejects the blade. They are speedy and ferocious as they are deployed in seconds. However, in order to return the blade into its enclosure, a lever needs to be pulled back thus requiring the use of both hands.

The result was a lot of friction that kept the blade from moving freely. I have since come up with a way to overcome this problem, but there are still a lot of other things to work out. To make it from steel, I could vastly reduce the size of the parts, but it would still be fairly large, mainly because of the size of the spring needed for it to work. Possibly drilling out the base of the blade and fill it in with a heavier metal, like lead, would increase the mass enough to carry the blade forward.

Painting T-Shirts Experiment. I've been meaning to do this for a while: paint a pattern onto a T-shirt with regular house paint. It happens that right now I'm w Making Drawers for Cabinets.

The next phase of the base cabinet project is to make the drawers, fourteen of them. The method shown here is probably my favouri An OTF knife is a knife whose blade extends and retracts from an opening at the front of the handle. When retracted, the blade is hidden within the handle. Such a knife is considered to be dual action when the slider, which is pushed forward by the thumb to extend the blade, can be pulled backward by the thumb, retracting the blade.

A single-action OTF knife is only able to automatically extend the blade. You have to pull the blade back into the handle by pulling a lever all the way to the back of the handle, which locks the blade in place until it is activated once again.

The mechanism inside a dual-action OTF knife is delicate and a patented device.
