Requires more skill than it should
The big question, does it work?  Yes, it does the job.  Question #2, is it easy?  On that I would have to say not initially, this tool will require a little practice, you need to develop a sense of “touch” to use this one to its full potential, though not nearly the level of skill needed to use a 3-corner file.<br />The file’s shank is round, so it is easy to let the tool roll side to side on the fret.  The previous model had a squared shank that gave a better sense of the correct orientation, when the flat side of the shank is is flat and level, the file groove will be properly oriented on the fret.  With this file, you have to feel for the proper orientation.<br />The wide groove can be used to flatten a single tall fret, or 3 or 4, much more than that you will want the leveling beam.  To level a fret takes a bit of pressure, but to actually crown the fret, you need to use a lighter touch.  Overpressure will definitely chew up the frets a bit.<br />I would like to see Baroque go back to the initial design, squared shank, fractionally deeper grooves, and milled safe edges on all the corners.  If I could get that tool for the same price, I would order one today.  At $28, I would consider looking around for other alternatives.
