There are three main types of pocket knives that differ primarily in how the blade opens for use and closes when not in use. In this article, we will look at the different types of pocket knives. If you want the best pocket knife for your needs, you can check out our guide.
Folding pocket knives
Folding pocket knives are still based on original pocket knife designs, even predating the Romans. In a folding pocket knife, the blade rotates around a pivot screw in the tool's handle, allowing it to be folded for storage and unfolded for use.
The blade of a folding penknife should fit neatly into the side of the handle when closed; most modern pocket knives also lock in the open or closed position for safety.
To open or "fold" the blade, there is usually a "flipper", a button, or a simple locking mechanism that the user presses to release the blade from the housing.
Retractable pocket knives
Retractable pocket knives, often referred to as "utility knives", have a more modern design in which the blade extends from inside the body.
When folded, the blade fits completely into the handle body and locks into place.
To extend the blade, pocket knives of this type usually have a "slider" - a button that is pressed and pushed forward to extend the blade, and pressed and pulled back to retract the blade.
Some new models are equipped with blades that automatically retract when contact with the cutting surface is broken.
Most modern retractable pocket knives are equipped with quick-change mechanisms that allow you to remove and replace blades with maximum ease.
Folding and retracting folding knives
Some pocket knives combine folding и retractable mechanisms for added security.
This means that the penknife must be opened and pulled out before the blade is exposed, reducing the risk of accidentally touching the sharp edges of the blade.
However, on some models, the blade automatically retracts when opened.
