How to Close a Pocket Knife

Slip Joint

Knives with a slip joint lock are one of the more casual and popular types of pocket knives. While not intended for heavy-duty tasks, these non-locking folding blades are still great for basic everyday activities. It’s very easy to close this type of pocket knife.

To close it, you’ll simply apply pressure on the back of the blade. Basically, any type of downward pressure on the back of the blade will close the knife.

Frame Lock

To close this type of knife, use your thumb to push the locking part of the frame out of the way of the blade. Once you move the locking part out of the way, you can simply apply pressure to the back of the blade to move it down to the closed position.

Liner Lock

This kind of pocket knife is similar to a frame lock. The main difference between a liner lock and a frame lock is that the liner lock has a different inner mechanism that holds the knife blade open.

The way to close a liner lock is similar to how to close a frame lock. But instead of pushing the frame lock aside, you’re going to look for the inner liner lock, usually found at the bottom of the handle. There will be a tab on this part of the liner that you can push aside with your thumb. That will free the blade, allowing you to push it down into the closed position.


This kind of pocket knife has a metal spine along with the handle that locks the knife blade into place.

To close a Lockback knife, look for the finger cut along the spine of the knife. Press on this exposed part of the spine to disengage the locking mechanism. This will release the spine and allow you to easily close the knife.


What should you check on a pocket knife before using it?

Whether you’re closing or opening your pocket knife, always be on the lookout for rust, damage, and any broken parts or malfunctioning locking mechanisms. These are things that could cause the knife to not work, be less effective, or even cause harm to the user.

Should you clean a pocket knife after each use?

The simple answer to that question is yes. You should always clean your pocket knife after each use. If your knife becomes dirty or wet, it can become dangerous to use. After you clean it, make sure you thoroughly dry it as well before you close the knife.

What safety precautions should you take with a pocket knife?

There are many precautions you need to take when using a knife. Make sure you educate yourself on knife safety before operating a pocket knife, as even the smallest ones can still be dangerous.

When you close the knife, make sure all your fingers are away from the blade. Remember that the blade will swing closed toward the handle of the knife, so be aware of where your fingers are when closing any pocket knife.
