Folding knives
The advantage of folding or pocket knives is their compact size. They have a blade that can be "folded" into the handle. Quality folding knives have handles designed for a comfortable grip, and many feature metal pocket clips for efficient carrying and transport.
The most common types of pocket knives include: EDC (Everyday Carry) knives, Multi-functional Swiss Army Knives, Rescue knives and a large portion of mushroom knives.

Pocket Knife Opening Mechanisms
There are several possible ways to open a pocket knife. The most common include: Thumb Stud, Thumb Hole, Flipper or Nail Nick.
Pocket Knife Locks
An important function of a folding knife is the lock, which secures the knife in the open position, thereby reducing the chance of injury while working.
Types of locks:
- Backlock: The lock is on the back of the handle and engages a notch on the blade, locking it firmly. It is released by pressing down on the rear end of the lock.
- Bar Lock (Axis): A system with a transversal bar that is pressed by springs against the blade's tang, locking it. It is released by pulling the bar toward you. This lock is also known as a Crossbar. The name Axis is used exclusively by Benchmade, as they hold the patent for this system.
- Button Lock: A locking mechanism operated by a button on the side of the handle. Pressing the button releases an internal pin, allowing the blade to be locked in the open position.
- Clasp Lock: An older lock often found on decorative knives, where a metal clip engages a notch on the blade. It is rarely used in modern cutlery, but can be found on traditional Spanish knives from Joker.
- Frame Lock: Part of the frame (usually metal frame) slides over and engages the blade's tang, locking it. It is one of the most reliable and strongest mechanisms.
- Friction Folder: A knife without a lock, held open only by the pressure of the fingers on the extended part of the blade. Security is minimal and only functions during grip.
- Liner Lock: A flexible metal liner inside the handle shifts and snaps behind the blade's tang upon opening, locking it. It is released by pushing the liner sideways.
- Slipjoint: A mechanism without a true lock, which uses a strong spring to hold the blade in the open or closed position. It is typical for traditional pocket knives and is not intended for demanding tasks.
- Viroblock: A system by Opinel that uses a rotating ring on the handle, which turns and locks the blade once it is open. It is simple and highly reliable.
Folding Knife Maintenance
Maintenance of a folding knife is important for its proper function. The knife must be cleaned after use, and it's advisable to lubricate the opening mechanism from time to time. You can find necessary knife maintenance accessories in this category.
