The small hole on a nail clipper also has some hidden practical functions. You could benefit greatly from them if you knew earlier.

Acts as a Screwdriver
In daily life, we often need a screwdriver to tighten or loosen screws. A nail clipper can help you do this without needing a professional screwdriver.
Simply stand the file upright and point the tip of the file at the screw. Twist, and the screw will come loose. A nail clipper can also be used to tighten screws and is extremely easy to use. If you need to tighten a screw but don't have a screwdriver nearby, you can use the file on the nail clipper as an alternative.
Replaces Pliers
If you need to bend stiff wire but don’t have pliers nearby, your nail clippers can serve as a substitute. It’s quite simple: if you look closely, you’ll notice a small round hole at the back of the nail clipper. Its primary function is to help you attach the clipper to a keychain easily.
To bend wire, thread it through the small round hole, then bend it back. This allows you to shape the wire effortlessly. The small hole serves as a stable anchor to bend the wire into any shape you desire, making it very practical.
Fixing Mosquito Coils
In the summer, mosquito coils are essential in many households. They often come with a stand, but what if the stand breaks, gets lost, or is insufficient for multiple coils?
A nail clipper can be used as a stand for mosquito coils. Simply separate the two parts of the nail clipper, stand the file upright, and secure the coil to the tip of the file. Place the setup on a plate, ensuring the coil is stable. Since nail clippers are made of stainless steel, there’s no risk of them catching fire.
Wire Stripping
Nail clippers can also strip wires with a simple method that anyone can follow. First, firmly press the nail clipper to remove the outer casing. Next, position the wire’s insulation between the cutting edges of the clipper. Press harder and rotate the clipper around the wire’s outer casing until it cuts through. The outer casing will then easily come off.
