Your nails are a crucial part of the interface with your guitar.

Long or short, the shape, finish and condition of your nails define the tone you get from your instrument.

So many players chase tone while ignoring these vital assets; those who do take care of ther nails often use a bewildering array of clippers, files, sandpaper and buffers to get the results they need.

Precision : Crystal² is the only nail file developed by guitarists, for guitarists.

Building on the success of our much-loved original Precision : Crystal, we developed Precision : Crystal² as the ultimate nail file - a single tool to shorten, shape and finish your nails to achieve and perfect your unique tone, quickly and consistently.

Etched into the highest-quality, hardened lead-free Bohemia crystal, our unique, perfectly even filing surface is calibrated to leave a finish perfect for great fingerstyle guitar tone - no need for further buffing or polishing.

Unlike other files with a sharp abrasive which tears at nails, causing chipping, tearing and cracking, our fine, etched surface turns nails safely and smoothly to dust, helping to keep them strong, healthy and in top condition.

You can use a Wolfram file freely in either direction across the nail (most files will damage the edge of the nail if unless used towards the centre) leaving you to focus on shaping.

Join the many professional guitarists all over the world who trust their nails - and their tone - to Wolfram Precision : Crystal.

"Superb, you've changed my life. The BEST tone from my nails ever. It's that good!"

Exclusive extras!

All Precision : Crystal² files come with our exclusive guide to nail shaping for guitarists, written with Tony McManus, and a cushioned hard protective case.

Understanding your nails and how their shape affects your guitar tone can be daunting - the more so because different natural nail shape and curvature mean that everyone's nails respond differently. Every Precision : Crystal² file comes with our 12-page full colour booklet covering nail shaping and technique for tone - written with Celtic fingerstyle master Tony McManus. Our exclusive guide explains how the nail and fingertip interact with the string, gives you pointers on what to look for and provides insight from Tony on how to shape nails to achieve your perfect tone.

We make Precision : Crystal² as tough as we know how, from double-tempered Bohemia crystal; however, we can't make them indestructible. Precision : Crystal² now comes with a unique cushioned hard protective case to help protect your file.

Precision : Crystal has the finest and most consistent surface available.

This comparison to three other popular glass files, at x400 magnification, shows the fineness and consistency of our unique fine filing surface.

The secret's in the surface

All glass nail files are not created alike! Precision : Crystal² is not just a generic glass nail file with a logo on it.

Precision : Crystal² is made for us, largely by hand, in a small, specialist workshop in the Czech Republic from genuine lead-free Bohemia crystal - the only glass with the special combination of hardness and flexibility needed to create the hghest-quality, most durable nail files.

Our unique filing surface is acid-etched directly into the crystal, in a proprietary process that creates the finest, most consistent surface available. This perfect surface, devoid of rough or sharp irregularities, imparts the beautiful nail finish unmatched by any other file, glass or otherwise.

Our Precision : Crystal² Pro files are the only crystal files available with two different filing surfaces - coarse and fine - optimised for guitarists with artificial nails.

Because the abrasive is not sharp, Precision : Crystal² can be used in any direction across the nail without chipping or splitting - leaving you free to concentrate on shaping for tone.

The edges of the file are shaped and polished by hand for a luxurious feel. The file is then heat-treated twice to temper it, raising the surface hardness by over 300%. This hardened filing surface will never wear down, while the file retains a supple core for maximum resilience.

Looked after, a Wolfram nail file will last for many, many years.

"The tone-boosting tool you never knew you needed."

"Ultra-lightweight, comfortable and easy to use with excellent results. In truth, nail sculpting is an art form … that becomes easier to master with such high-quality files."
