Emery Boards vs. Metal Nail Files: See the Difference

If you are a nail enthusiast, you probably have a collection of nail files in your manicure kit. But do you know the difference between emery boards and metal nail files? Which one is better for your nails? In this article, we will compare these two types of nail files and help you choose the right one for your needs.

What are Emery Boards and Metal Nail Files?

Emery boards are the most common type of nail file. They are made of cardboard or wood with a layer of abrasive material (usually emery, a type of sand) glued to it. Emery boards come in different grits, or coarseness, depending on how much filing you need to do. The lower the number, the coarser the grit. For example, a 100-grit emery board is very coarse and suitable for removing a lot of length, while a 240-grit emery board is fine and suitable for smoothing and shaping nails.

Metal nail files are made of steel or other metals with tiny teeth that file the nails. They are usually very durable and can last for a long time. Metal nail files are also very strong and can file hard, thick, or artificial nails. However, they can also be very harsh and damage the natural nails if used incorrectly.

How do Emery Boards and Metal Nail Files Work?

Both emery files and metal files work by grinding the nail and creating friction. However, they do it in different ways. Emery files work by tearing the end of the nail as you slide it across the tip of the nail. This produces a rough edge that can catch on things and cause splitting, peeling, or chipping. Metal files work by scraping the nail and removing thin layers of the nail. This produces a smooth edge that can seal the nail and prevent moisture and dirt from entering the nail.

Which One is Better for Your Nails?

The answer depends on your nail type, condition, and preference.


Emery boards are better for natural nails that are thin, weak, or fragile. They are also better for shaping the nails and creating curves or angles. However, emery boards can also cause damage to the nails if used too often, too roughly, or in a back-and-forth motion. Emery boards are also not very hygienic, as they can harbor bacteria and fungus in the pores of the abrasive material. Therefore, you should replace your emery boards regularly and avoid sharing them with others.

Metal nail files are better for artificial nails that are thick, strong, or hard. They are also better for removing a lot of length and creating a straight edge. However, metal nail files can also cause damage to the nails if used too aggressively, too frequently, or in the wrong direction. Metal nail files can also create heat and friction that can burn or weaken the nails. Therefore, you should use your metal nail files gently and sparingly and file in one direction only.

How to Choose the Right Nail File for You

The best way to choose the right nail file for you is to experiment with different types and see what works best for your nails. You can also have more than one type of nail file in your kit and use them for different purposes. For example, you can use a coarse emery board to remove length, a fine emery board to shape the nails, and a metal nail file to smooth the edges. You can also use a crystal or glass nail file, which is a type of nail file that is gentle, durable, and hygienic. Crystal or glass nail files work by sealing the nail and preventing splitting or peeling. They are suitable for all types of nails and can last for a long time.

How to Use a Nail File Properly

No matter what type of nail file you use, you should follow some basic guidelines to use it properly and avoid damaging your nails. Here are some tips to keep in mind:

• Wash and dry your hands and nails before filing.

• File your nails when they are dry, not wet. Wet nails are more prone to breaking or tearing.

• File your nails in one direction only, from the side to the center. Do not file in a back-and-forth or sawing motion, as this can cause friction and heat that can damage the nails.

• File your nails gently and lightly. Do not press too hard or file too fast, as this can cause the nail file to slip and injure your skin or cuticles.

• File your nails in small strokes and check the shape and length frequently. Do not file too much or too little, as this can affect the balance and symmetry of your nails.

• Clean and sanitize your nail file after each use. You can use soap and water, rubbing alcohol, or a disinfectant spray to remove any dirt, debris, or bacteria from your nail file. You can also use a nail brush or a toothbrush to scrub the surface of your nail file.

• Store your nail file in a dry and cool place. Avoid exposing your nail file to heat, moisture, or sunlight, as this can affect its quality and performance.

Conclusion

Emery boards and metal nail files are two types of nail files that have different advantages and disadvantages. Emery boards are better for natural nails that are thin, weak, or fragile, while metal nail files are better for artificial nails that are thick, strong, or hard. However, both types of nail files can also cause damage to the nails if used incorrectly or excessively. Therefore, you should choose the right nail file for your nail type and condition, use it properly and carefully, and clean and maintain it regularly. You can also use a crystal file, which is a gentle, durable, and hygienic type of nail file that is suitable for all types of nails. By following these tips, you can achieve beautiful and healthy nails with the help of your nail file.
