Imagine a weekend you’ve planned a casual get‑together with friends, and you want your nails to look flawless without spending a fortune at a salon. The secret? A simple nail file in the right hands. Below, we’ll walk you through every detail, from choosing the best file to the best filing technique, all in plain South‑African English—so even a 5th‑grader can follow along.


Get to Know Your Nail File

Not all nail files are created equal. The two most common types are:

TypeWhat It DoesTypical Price
Emery BoardFine scrubbing action, great for quick shapingR80–R120
Mesh FileCoarse to medium grit, tough on thick nailsR100–R140
Diamond FileVery sharp, perfect for polish removalR150–R200

If you’re buying your first file, pick an emery board. It’s inexpensive (around R90) and perfect for beginners.


Choose the Right Grit

Grit determines how much material you’ll remove:

  • Coarse (80–120 grit) – Removes big chunks, best for wide or tacky nails.
  • Medium (120–200 grit) – Great for regular maintenance.
  • Fine (200–400 grit) – Smooths the nail edge for a glossy finish.

When looking for a file at a local store, ask the staff which grit they recommend for everyday care. Most people find medium grit the sweet spot for daily use.


How to File: The Three‑Step Routine

  1. Prep Your Hands

    • Wash your hands with lukewarm water and soap.
    • Gently pat them dry—wet nails are more fragile.
    • If you prefer, apply a base coat; it protects your nails while you file.
  2. Keep the Nail Straight

    • Hold the file at a 45‑degree angle to the nail plate.
    • Use gentle strokes (no more than 5–7) in one direction—toward the cuticle, not back and forth.
    • Think of a bike wheel: smooth, rotating movements are the key.
  3. Finish with the Polish Edge

    • After you shape the length, use the file’s tiny corner to fillet the nail’s edge, giving it a subtle polish.
    • If you ended up with a rough spot, a fine‑grit file can smooth it out.

Quick tip: File each nail on the same side of the hand. If you feel a gap in the file, it will keep a consistent angle across all nails.


Common Mistakes (and How to Fix Them)

MistakeWhy It’s BadFix
Shaving back and forthScratches and splitsKeep a single direction
Filing over a cuticleIncreases risk of infectionStart a few millimetres away
Using a very coarse fileCreates uneven nailsSwitch to medium or fine grit
Holding the file too tightlyBurns the nail bedUse light, steady pressure

If you’ve made several of these blunders, a quick wash, a rub of clay soap, and a top‑coat can rescue your nails.

The Science Behind a Good File

What makes a file work? It’s the uneven surface that exfoliates small nail grains. The harder the file’s grit, the more material is removed in a single swipe. Nail technicians have a rule: “Skin‑like nails need a gentle touch.” That’s why we recommend starting with a moderate grit and working gently—you’ll keep your nails healthy and strong.


How to Keep Your Nail File in Top Shape

  1. Wipe After Use: A damp cloth with a little dish soap removes nail dust.
  2. Store Upright: Prevent the file’s edge from worn‑away contact with the box.
  3. Change Grits Regularly: If one side becomes dull, switch it out.
