The small hole is one example.
Why the Hole Exists
One commonly discussed purpose of the hole is to assist with more precise nail trimming, especially in situations where accuracy matters.
Unlike regular nail cutting, dealing with uneven nail edges or troublesome corners often requires more control. The hole can help guide a small section of nail into a specific position before trimming.
Because the opening is small, users can focus on a limited area rather than clipping a large section all at once. This may help create cleaner, more controlled cuts.
For people who prefer detailed nail grooming, such precision can make a noticeable difference.
Instead of repeatedly clipping and reshaping, they can target specific sections more carefully.
This level of control is one reason many grooming enthusiasts appreciate the feature after discovering it.
