Guitar Fret File, Double-Side Fret Crowning File, Professional High Carbon Steel Design Fret File for Electric, Acoustic and Bass Guitars - MD, LG, XL Frets with Clean brush

Very nice looking tool, has many difference from the photos at least for me, the teeth feel good but a couple teeth have some damage.My gripes the tool showed up in some weird blue mesh, but that I dont care about that, it was how nasty the tool was, covered in what I assume is old cutting fluid or CNC fluid that dried and went rotten, the now crusty messy tool had a horrible smell to it also, just not the way to make customers. Idk how many your selling but to toss them all over water then rub and package can't be that rough. compared to what some may assume is a used tool resold, which this maybe used its have many dents and dings in it but could just be from manufacturing in a small shop. Also the tool had a very cool protective coat on it so maybe that was what the fluid was a etching fluid, idk what it was just nasty all around, was not very hard at all to clean off and once I had it clean, the coat on it adds grip and corrosion protection and the lettering is gold which makes the tool look amazing, except the damage to the tool and the rotten mayo hand shake they gave me. But I have about 47 more frets to do and my next guitar had much harder frets so ill update once done.

I'm giving this 5 stars because it seemed to make a big difference on a guitar that probably could stand to have the first 5 frets replaced. It cut a nice shoulder on quite a few bad spots. Through my magnifying glass, the before and after difference was very clear. I would like to see how it works on frets that were better or on new frets. The file worked well and did not require any pressure. I am inclined to believe what they claim as a difference between this type of file and those that use diamond dust.

I have a cheaper Chinese Crowning file from a simple luthier kit I bought. It's not aggressive and leaves a very smooth finish. This file IS aggressive, so it quickly re-crowns, but it leaves a pretty gritty surface texture behind. Frets require quite a bit of polishing to smooth them out after using this file. It works well, and is a good tool, but leaves a rougher finish behind post-use.

This is a great file, I will definitely order another one when I wear this one out.

perfect little tool at a reasonable price. I had to take .025 off my new frets and this kept them perfectly shaped.

So I did some crowing with this tool and my results were not all that great. It seems to be a copy of the "Fret Guru" which I probably will end up purchasing. Since I haven't used the Guru yet I can't directly compare the two but I'm hoping it will be as good as the reviews and youtube videos show. Save your money and get the Z file from Stew or the Guru. You'll be happier in the end. I used it on a low budget guitar so I wasn't too worried if it marred things up. I'm glad I did. I just don't think the file part has the correct geometry to get a nice rounded dome shape we all want.

If it was possible to give zero stars I would. DO NOT BUY, waste of $. Oversized slots, dull, does more harm than good. Product should be removed. Not even a good beginner practice tool— i went back to my wood block and 600/300 strips until I purchase proper crowning tool (and boy was it a revelation!). Avoid this.

A quality fret file that gets the job done!!
