About Nail Files
From Wikipedia: “A nail file is a tool used to gently grind down and shape the edges of nails. They are often used in manicures and pedicures after the nail has been trimmed using appropriate nail clippers. Nail files may either be emery boards, ceramic, glass, crystal, plain metal files or metal files coated with corundum (sapphire).“
Metal | Glass | Fibre – What’s best?
To keep your natural nails the length and shape you want you’ll have to occasionally shape them with a file or emery board. It’s also the first thing you’ll reach for when you have a torn nail that snags in your clothing. (You don’t bite the piece off do you??)
There are quite a few options when it comes to nail files including metal, fibre (emery) and glass. Metal files can be quite harsh and can cut or puncture if not used with care. They are generally not recommended by Nail Professionals. Glass files are OK but are not flexible and do not provide the padding (or ‘give’) of a professional fibre type nail file. Professional files come in various ‘Grit Sizes’. The rougher ones have fewer, larger pieces of grit on their surface and are ‘Lower Grit’ Examples of rough, low grit files are 100 and 180.
Low grit files are usually used for quick filing of acrylic nails before finishing them off with a higher grit.
For natural nails and for general trimming you should be using no less than a 240Grit file.
You can finish them by smoothing with a high grit file like 1200 or even 2400.
Very high-grit files are called ‘Buffers’ and they are used for making the nail edge as smooth as possible. If you have any questions or are unsure about the proper procedures to follow when shaping and filing your nails, please talk to your Nail Technician.
