Assisted opening knife: what is it?

Print anything with Printful



Assisted opening knives are small pocket knives with a spring mechanism that helps open the blade. They require effort from the user to open and are not considered switchblades. They are useful for manufacturing, shipping, and emergency situations.

The assisted opening knife is usually a relatively small pocket knife that can be opened easily and quickly with one hand. These knives are distinguished from other types of one-handed opening knives in that they include a mechanism, usually a spring function, that assists in opening the knife. Unlike switchblades, however, this type of knife requires some effort on the part of the user, rather than simply pressing a button. An assisted opening knife is a great knife to use as a tool in manufacturing or shipping, as it can be easily operated one-handed.

Sometimes called a spring knife or a quick release knife, this knife is usually designed as a folding knife that can fit in a person’s pocket. The blade folds into the handle, just like other flip lock knives. Most have a small thumb pin that can be used to apply pressure to the blade and open it from the handle. Unlike other locking knives, however, an assisted opening knife has a mechanism inside the handle that assists in this opening process.

The mechanism tends to hold the knife blade in place within the handle while it is closed. Opening the knife requires a user to apply force to a thumb stud or other part of the blade to begin opening the blade from the handle. Once you reach a certain point with the blade, usually around 30°-45°, then the internal mechanism takes over and opens the remaining blade. This is usually a spring-loaded process and the blade can open quite quickly and lock into place.

An assist-opening knife is typically not considered a switchblade and may be legal in many countries where switchblades are banned. The difference, albeit subtle, between these types of knives is that a switchblade can be opened using a spring mechanism by simply touching a button, whereas an assisted opening knife requires effort and strength on the part of the user to open the knife . These knives can be excellent tools for use by people working on factory lines or in packing and shipping or receiving shipments of various products. Because these knives can be opened quickly and easily with one hand, they are excellent for use in cutting open pallets of produce or for emergency situations such as a person having a glove or article of clothing snagged in a car.
