Review: Leighton Denny - Crystal Nail File

I have done a comparison of the OPI one and the Leighton Denny one here.

This nail file has a rounded end and is exceptionally smooth, you could run this over the finest of tights and it would not snag them. You can use this on your nails and they won't be clicking off anything and everything.

Very gentle on nails, and seals the end of the nails against water getting in and weakening / damaging / splitting nails. I also find that this file having a rounded end is particularly useful, especially as I am a clumsy person, whereas I have stabbed myself accidentally numerous times with the OPI one.



The higher the grit, the less course the file is. This having a no grit means it takes a while to file down the length of your nails.  Leighton's crystal nail file doesn't have a grit rating as it is that fine. It is made by dipping the crystal file in to acid which eats away at the crystal causing the fine texture to it rather than with a glass nail file whereby the glass is sprayed with sand to achieve the gritted texture. As such the surface of a glass file wears away whereas with this crystal one it does not, you can simply wash it and the surface will be as good as new. The surface of the file is guaranteed for 25 years.

Comes packaged in a flip lid tin pack which is perfect for protecting the file.

The dimensions are as follows:
Length - 135mm
Width - 11mm
Depth - 3mm

Leighton Denny Vs OPI - Crystal Nail Files

In the market for a crystal nail file? Don't know which is better? Here's a bit of a guide.

Why not use a emery board made of cardboard?

The grit is usually finer, meaning it helps improve the health of your nails. Helps against splitting, peeling and chipping. It means that your nails are less likely to snag and click tights too. With a crystal nail file you can file in any direction you like whereas with a traditional cardboard one you can't. Simply wash with warm water and dry and your nail file is good as new.

Why would I want a crystal nail file over a glass one?
A glass nail file is made in the same way as traditional emery boards, sandblasted. A crystal nail file is dipped in acid and so the grit is permanently etched on to the file. A glass one will wear down the same was as a cardboard one.

What is a grit?
A grit rating is the amount of sand per square cm. The higher the grit rating the smoother the file and the gentler it is on your nails.

OPI- Crystal Nail File
Ever so slightly longer than the Leighton one. This has a sharp end which is a bad thing for clumsy people like myself. If you do like a metal nail file with a point then I imagine you would like this. The grit on this is more rough. You can file your nails with this and take off a lot of length quickly. Comes packages in a plastic round tube, quite rustic but cheap feeling and easily breakable. Grit - 240.

Bottom Line
I've owned the OPI file for over two years and Leighton Denny's for around a year and I find I use them both. OPI for taking down length and Leighton's for smoothing the edges and filing the free edges. If I had to choose between the two I'd opt for Leighton's because even though it is slower at removing excessive length usually I just use it to tidy up the free edge as I quite like to keep long nails. The finish isn't as smooth with the OPI one either. You don't need both files.
