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!
What It Means If Your Nails Have a Half-Moon Shape
Have you noticed a white half-moon shape at the base of your fingernails? This feature, known as the lunula, is more than just a natural design—it’s a vital part of your nail and can provide important clues about your health.

The term “lunula” comes from the Latin word for “little moon,” and in many traditional health practices, including Chinese medicine, it’s used as an indicator of overall wellness. Changes in the lunula, such as its size, color, or disappearance, can reflect shifts in your health status. Interestingly, when health improves, the lunula tends to return to its normal appearance.
What Does the Presence or Absence of Lunulae Say About Your Health?
According to medical experts, having eight to ten clearly visible, milky white lunulas on both hands is a sign of good health. The brighter and more defined the lunulas, the stronger your health.

Typical Lunulas
People with healthy, white lunulas tend to have strong immunity, good overall health, and higher energy levels. A reduction in the size or number of lunulas, however, may indicate a decline in these areas. If the lunula is only visible on your thumbs, it could suggest physical weakness and a greater susceptibility to illness.
Missing Lunulas
The absence of lunulas (a condition sometimes referred to as “nolunula”) has been linked to various health concerns. Studies suggest it may be associated with conditions like iron deficiency, chronic kidney disease, depression, thyroid or pituitary disorders, and a potential deficiency in vitamin B-12.
If you notice changes in your lunula, it’s worth checking your vitamin B-12 and iodine levels, as well as having your blood pressure and thyroid function assessed. In short, your lunula can serve as an indicator of your overall health, and any significant changes should be taken seriously and verified by a healthcare professional.
