In the realm of everyday tools, a pocket knife reigns supreme as a versatile companion. Its ability to slice, cut, and shape makes it indispensable for various tasks. However, understanding the proper technique for closing a pocket knife is crucial to avoid injury and ensure its longevity. This article will guide you through the steps necessary to shut a pocket knife safely and effectively, ensuring that your trusty blade remains a reliable tool for years to come.
Before delving into the techniques, it is essential to understand the anatomy of a pocket knife. Most traditional pocket knives feature a blade that rotates on a pivot point and is secured by a locking mechanism. This mechanism can vary depending on the knife model, but the most common types include a liner lock, a frame lock, and a back lock. Identifying the locking mechanism on your knife is crucial for determining the correct method of closing it.
With the preparatory knowledge in place, let’s embark on the practicalities of closing a pocket knife. Safety should always be the foremost concern; therefore, ensure that the knife is pointed away from you and others before you begin the process. Grip the handle firmly with one hand while using your thumb or finger from the other hand to disengage the locking mechanism. Once the blade is loose, carefully fold it back into the handle while guiding it with your fingers. Finally, ensure that the locking mechanism is fully engaged to secure the blade and prevent accidental opening.
Identifying the Locking Mechanism
Pocket knives employ various locking mechanisms to keep the blade securely in place when open. Understanding these mechanisms is crucial for safely operating and maintaining your knife.
Back Lock
The back lock features a spring-loaded bar that engages a notch on the back of the knife’s blade. When the knife is opened, the bar slides into the notch, preventing the blade from closing accidentally. To close the knife, you must depress the bar using your thumb, allowing the blade to retract.
Liner Lock
A liner lock consists of a thin metal liner that rotates within the knife’s handle. When the blade is opened, a portion of the liner engages a tang on the blade, providing a solid lock. To close the knife, you must push the liner out of the way, allowing the blade to fold down. Liner locks are widely employed due to their simplicity, strength, and ease of use.
| Locking Mechanism | Operation |
|---|---|
| Back Lock | Press thumb against spring-loaded bar to disengage |
| Liner Lock | Push liner out of the way |
Releasing the Liner Lock
The liner lock is a simple and effective locking mechanism commonly found on pocket knives. It consists of a spring-loaded liner that engages with a notch in the blade when the knife is opened. To release the liner lock and close the knife, follow these steps:
Step 1: Check the Safety Feature
Some liner lock knives have a safety feature that prevents the lock from being accidentally disengaged. Locate this safety and disengage it, if present.
Step 2: Depress the Liner
Using your thumb or another finger, apply pressure to the liner that corresponds to the side of the knife’s handle opposite the blade. This will depress the liner and disengage it from the notch in the blade.
Step 3: Carefully Pivot the Blade
While maintaining pressure on the liner, carefully pivot the blade closed with the other hand. Keep your fingers clear of the blade’s path to avoid injury. Once the blade is fully closed, the lock will re-engage automatically, securing the blade in the closed position.
| Release Method | Description |
|---|---|
| Thumb Pressure | Use your thumb to depress the liner and pivot the blade closed. |
| Fingernail Depress | Use your thumbnail or fingernail to push down the liner, allowing you to close the blade. |
| Small Tool | If possible, insert a small tool, such as a toothpick or thin screwdriver, into the notch to depress the liner instead of using your fingers. |
Disengaging the Frame Lock
Disengaging the frame lock is the most common method for closing a pocket knife. Here’s a detailed guide:
1. Position Your Thumb
Place your thumb on the back of the knife, near the axis point (the part where the blade pivots). Ensure your thumb is behind the frame lock (the small metal tab that locks the blade in place).
2. Apply Pressure
Gently press your thumb against the frame lock. You should feel it rotating as you apply pressure.
3. Lift the Blade
As you press the frame lock, simultaneously use your other hand to lift the blade slightly. The blade should start to move.
4. Disengage the Lock
Continue pressing the frame lock as you lift the blade. At a certain point, you will feel or hear a click. This indicates that the frame lock has disengaged, and the blade is now free to close.
| Step | Action |
|---|---|
| 1 | Position your thumb on the back of the knife, near the axis point. |
| 2 | Apply pressure to the frame lock with your thumb. |
| 3 | Lift the blade slightly with your other hand. |
| 4 | Continue pressing the frame lock until you hear or feel a click, indicating that the lock has disengaged. |
Depressing the Back Lock
The back lock is a common locking mechanism found on many pocket knives. To depress the back lock and close the knife, follow these steps:
1. Grip the knife firmly, with your thumb resting on the back lock.
2. Apply pressure to the back lock and push it down towards the handle.
3. As you push down on the back lock, the blade will begin to fold into the handle.
4. Continue to push down on the back lock until the blade is fully closed.
5. Once the blade is closed, the back lock will engage and hold the blade in place. To ensure the blade is securely locked, gently shake the knife to check for any movement.
| Step 1: Grip the knife firmly, with your thumb resting on the back lock. |
| Step 2: Apply pressure to the back lock and push it down towards the handle. |

Overcoming Axis Locks
Axis locks are commonly found on Benchmade knives and feature a spring-loaded bar that engages with the tang of the blade. To close a knife with an axis lock:
- Position your thumb on the axis lock tab.
- Push the tab forward while pulling back on the blade.
- Once the lock is disengaged, slowly lower the blade.
Assisted Openers
Assisted openers use a spring to assist in opening the knife. To close a knife with an assisted opener:
- Gently press on the thumb stud or flipper tab.
- Once the blade is partially open, manually close it by pulling back on the blade.
- Be careful not to use excessive force, as this can damage the spring.

Friction Folders
Friction folders, also known as back-lock knives, have a spring-loaded liner that locks the blade in place when it is opened. When the blade is closed, the liner disengages from the blade, allowing it to fold freely. Friction folders are relatively simple to operate and maintain, making them a popular choice for everyday use.
Slip Joints
Slip joints are the oldest and simplest type of pocket knife. They consist of a blade that is held in place by a spring-loaded joint. When the blade is opened, the joint locks the blade in place. However, when the force is applied to the blade, the joint can “slip,” allowing the blade to fold. Slip joints are less secure than friction folders or lockback knives, but they are also lighter and more compact.
