Excellent tool that works well... : - )
Works very well. It is an aggressive cut. So, keep that in mind. Mark the top of your frets with a magic marker to gauge depth of cut.

Great tool for hobby techs or personal use
This is a good set for a hobby guitar tech on a budget. I've used it on a couple Fender American guitars, an Epiphone, and a couple budget acoustic guitars. It does a great job of crowning frets after a complete fret level, or after fixing individual high frets. You definitely need to polish after. But that's something you should do even if your frets are already crowned. There are definitely better tools for the job. But the difference does not warrant the extra $100-$300 if its just a hobby, or for taking care of your own guitars. You need to sharpe the top of the frets to make sure you crown it and not lower it by going too far. Then polish the ink off after your finished crowning.

Not bad but there’s better. Take a class about fret leveling and your mind will be opened.
You get what you pay for. It works well but like stew mac files there’s a lot of chatter to sand out. Nearly IDENTICAL to the Fret Guru Dagger file. Which are basic and still missing the true solution of why mechanics and craftsmen make their own files. These are nice attempts, good quality, this fret dagger ish file and have a use for crowning… quickly. Or really flat frets you had to level down to get the divots out. But you’ll have lots of scratches. If not the case, Less is more, let the tool do the work for you. Use another tool or a triangular file from J Hernandez of HomeWrecker Pickups and The Tone Consultant. Buy and sign up for a personal lesson and have the better understanding form a true expert. He will actually show you how to use all the different files, point out their shortcomings and also show you that you shouldn’t have very many scratches when crowning. Why his file set tri , diamond 4 side, and diamond concave are essential. Like music nomad. Because it’s the same real ones who do R&D on eachothers products together, they just aren’t boasting about it on socials. Get this, music nomad and J from HomeWrecker pickups The tone consultant. If it’s a QC environment at a company, you need a concave diamond file for quick jobs. Fret mills not the art of a level/crown/maintaining integrity of the peak. If you yourself want to follow the influencers, use a concave diamond file. Those GuitarTechnician guy, who put put black lights and seek for finish flaws on $500 guitars rather than just play them like a real player. I got tired of the same old but more neurotic person who just learned behind a computer and never stepped foot into a shop and put skin in the game music, nomad or J Hernandez, who are real veterans in the game with a lot of people behind them. Get many different files and take a lesson! Keep an open mind. I thought I’d write this review from experience, and taking the advice from buying a super high-quality file, from someone who knows what they’re doing and, simplified the process tenfold with each file. what influencers have completely missed the boat on. Let alone what integrity of the crown is after round over. Again, keep an open mind and happy raspy fret crowning everybody! It could be a different procedure, but if it’s the same results at the end and you’re happy. Keep on going and gain the experience and collaborate with other others! CC

Works quite well
Works quite well, not as aggressive as some have commented

Cheap imitation?
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.

This has never happened before.
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.

Bad copy of a good item
This is a copy of the Fret Dagger. It is poorly made. Smells horrible! And the worst part is the way the file cuts. It does not have the same cutting edges as the original item. You will pay less money for this file but you will need to put a lot more time to get decent results. I do not recommend this and will be returning this.

Es casi igual a la de "Marca Famosa"... Y hace el mismo trabajo en los trastes a la mitad del precio

Quite good performance, each different fret crowning file I use has its unique positive and negative functions. This one is very sharp and leaves a smoother crown radius finish than other crowning files I've tried. This file's corner edges however are also very sharp and may cut into a fingerboard if you tip too far off the center radian which I can do with my other favourite file to form and position a stubborn crown. I did finish grind the aforementioned sharp edges to avoid slip ups. It's also more comfortable to shrink tube a handle wrap on there, those edges are also quite sharp and can hurt while doing 24 frets and 48 fret ends. A pretty good tool which can be developed and finnessed by the user.

It is not as advertised. It is very roughly cut unprotected steel. It already shows signs of corrosion before I take it out of the package. Does not look like the picture in the ad.
