Nearly every household has a pair of nail clippers. These handy tools are primarily used for trimming nails, and sometimes even snipping thread. But have you ever noticed the small round hole on some nail clippers? You might be surprised to learn it has a few clever uses! Many people don’t know about this hidden feature, but once you understand its purpose, you’ll want to give it a try. Let’s explore what it can do!
One use for the small hole is to attach a keychain to your nail clippers. By securing it with a keychain, you can keep the clippers with your keys, ensuring you’ll never misplace them (unless all your keys go missing). Some nail clippers even come with a small chain specifically for this purpose. However, those chains can sometimes detach easily, so it’s often better to attach a keychain directly through the hole for a more secure hold.
The small hole can also help with wire bending. By threading wire through it, you gain extra leverage to bend the wire with ease, reducing the effort needed. This trick is especially helpful when you need to bend or break wire without putting too much strain on your fingers.
Another handy feature of nail clippers is the small metal piece that often surrounds the hole. This piece can be used for cleaning dirt from under your nails but also doubles as a mini screwdriver for small screws. It can save you in a pinch when you don’t have the right tools on hand—just give the screw a few turns, and it’ll loosen up.
Lastly, the sharp edge of the nail file on your clippers can even be used to slice through packing tape on boxes. With these tips, you can get much more out of your nail clippers than just trimming nails!
Why is that?
The Answer is:
If a vehicle drives in a straight line at high speed for a long time, it will cause the driver’s vision to become fatigued, attention to be distracted, and even lead to drowsiness, which is unsafe. Therefore, driving on a road that changes from straight to curved will stimulate the driver’s concentration better.
Not to mention, builders also consider that a powerful vehicle can easily climb a steep road, but a heavily loaded truck or a passenger vehicle cannot. Moreover, a road with a straight, steep incline is extremely dangerous when descending, as it is difficult to control speed. A steep incline can also affect the driver’s visibility, making it hard to see ahead.
When designing curves, builders try to increase the curve radius and reduce centrifugal force, allowing vehicles to handle the turn more easily even at high speeds.
In summary, while winding roads may take more time to travel, they ensure greater safety. Driving on a steep, straight road is akin to playing a dangerous game that most people wouldn’t want to try.
