 Our fret crowning files are the traditional tool for profiling frets after a fret levelling job and come with a custom, ergonomic 60mm mahogany handle.  All three corners of the file have been precision ground to create a safe edge that will not damage your fretboard as you work (although we do recommend masking off your fretboard in any case).

Check out the video below for an overview of our fret crowning tools and how to use them.

This video was published in 2013 since then many tool designs have changed and some of the files are sourced from different manufacturers.  An up to date video coming soon.

    The handle on this is what sets it apart. The facets make it really ergonomic. The file is awesome as well with the flat edges making it easy to set it down and round over until you start biting the fret and then smoothly filing away what you need. Great tool.

    Fantastic! Love the handle! The cut is smooth compared to their competitors’ files. U.S. buyers…. plan ahead. Shipping takes about a week. Not a huge deal but does bring a project to a halt if you’re ready for fret dressing.

    Well made, comfy to use, and performs brilliantly. Thanks!

    I really like the way the handle fits in the hand, and the quality of the file itself is nice. The design makes it really easy to do good fret work even for a novice like myself. I will definitely be purchasing more tools from Crimson.

    Lovely file, works well on my ukulele’s little frets. The handle sets this file apart from the rest.

    Right from the packaging to the tool itself, pure class. In all fairness, the item I received has “Made in India” inscribed on the metal portion. I guess the handle and assembly may be done in the U.K. The workmanship and finishing are the best of any tool I’ve bought so far (like other users have stated, the handle is wonderful.) Well done.

    Really good usable tool for re-crowning frets even for a novice like me. Nice ergonomic handle feels good in the hand for precise work. Just done a bit of work on a high fret I had on my guitar and re-crowned it with this file and finished of with the Crimson fret rubbers. My guitar is now playing better than ever and saved myself a trip to the guitar repairers! The file was well packaged and promptly delivered. Good service Crimson!

    I’ve never really been all that keen on the traditional crowning files, but the good people at Crimson helped me make up my mind!
    I’m really happy that I took a chance on this Traditional crowning file, because it’s super and really great to use!
    As others also say, the handle is great and the file feels really good in my hand, when working it!
    The cut is smooth and the flat fret tops is quickly and easy rounded back up!
    I’ll go most of the way with the traditional crowning file, then followed by a modern concave crowning file – just to smooth it all up! I’m very, very pleased with that!

    If you are not used to the technique, using this traditional crowning file, then you’ll have to start out slowly and work your way up – until you are more used to it.
    The safe edges on the file will really help you to guide the file across the frets, and make sure that you are not damaging anything on your guitar!

    Quality tools, made from the best materials and worth every penny, really!

    You can’t go wrong here!

    Just perfect in the hand. Exactly as advertised!

    Just received mine in the mail. This is an excellent file for a really cheap price. It came quite quickly, considering it was coming from the UK to Canada. Much quicker shipping than StewMac and was more than half the price of anything comparable. I’ve put off buying anything from Crimson before, but I will definitely not hesitate again in the future.
