La mejor herramienta para coronar

After 3 refrets with this crowning file, I can recommend it highly. The design of the tool virtually guarantees a very fine crown everytime. With two different sized grooves, it can cover most any size fret and does handle stainless steel frets very well. The one caveat I would add though is for first time users. Make sure you use the correct size for your fret job and always clean your file often to remove any debris that could hinder the workability of the file. Ergonomic and well weighted to allow you to let the tool do the work. Highly recommended

Super outil qui m'a permis de faire finaliser la planimétrie de ma guitare et donner une seconde jeunesse à ses frettes ! La lime est ergonimique et simple d'utilisation.

It's unfortunate Music Nomad tools are super expensive in Canada (curse the exchange rate and shipping costs from USA) . Had a total fret board to do, so had to bite the bullet and purchase the tool. It works, does not damage the fret board. If you use it as described in their videos you can't miss it up. Using this tool minimizes the human error factor, its basically fool proof. It saved time, only hours to use vs. days by other methods. It is a quality tool and highly recommended. I don't believe there is anything else available that would do as good a job for what I needed to do.
