Gear Review: The Soundfile

The Nail File I Didn’t Know I Needed

by Leonardo Garcia

Last Christmas, while hunting for stocking stuffers for my sons, I stumbled across a website called The Soundfile. I wasn’t expecting much—after all, a nail file is about as straightforward as it gets. But The Soundfile’s Next Generation Glass Nail File is one of those small but game-changing tools that makes you wonder how you could’ve gone so long without it.

From the very first use of the Next Generation Nail File, I realized its existence wasn’t just a marginal upgrade. The file creates such a fine, polished ramp that I felt using fine sandpaper out of sheer habit afterwards was unnecessary.

What sets this file apart are two things:

  • Thickness & Rigidity: Unlike the flimsy feel of the standard sapphire file, this one is thick and completely rigid. That stability translates directly into a straighter, more controlled ramp.
  • Transparency: You can literally see through the file as you work, which provides a unique level of precision. It’s like having an X-ray view of what you’re doing.

For over 35 years, I had been using traditional sapphire nail files. They did the job, but never perfectly. The thinness and slight flexibility of sapphire files meant that achieving a truly straight, polished ramp was always a compromise. If you are wedded to the use of a sapphire metal file, The Soundfile also has a thicker sapphire file, which is a step above the usual.

It’s rare to find a tool this simple that so clearly outperforms what came before it. Sometimes the best discoveries come when you’re not expecting them. For me, the Next Generation Nail File was one of those discoveries.

If there ever was an argument for practicing rest stroke scales, I think Marco Tamayo would settle it. Though the video below is casually shot by a student asking about fingering solutions to Joaquín Rodrigo’s Aranjuez and Joaquín Turina’s Soleares, there is gold in it. Just observing the complete ease and extreme mastery of Marco’s approach reveals how much care and thought has gone into every single action.

Here is another valuable video where Marco gives us details on nail shaping and filing. Again, probably one of a handful of videos that are worth watching on the subject.
