FretGuru Guitar Fret Crowning File - Dual Sided Dagger 2.0 - MD and LG/XL - Ideal for Frets between .080" to .110" wide - Professional Luthier Tool for Electric, Acoustic and Bass Guitars

I don't normally do reviews...but when I find a new tool that does an old job well, I'll make an exception. My first impression? Elegant, simple, nicely refined surfaces. The handle edges are rounded, comfortable, and the swell at the end makes for a nice palm grip. This is a solid piece of tool steel with a concave rounded edge that as far as files go, is sharp and effective at crowning frets. I will note though, too much pressure will create a washboard surface on the fret...so let the file do the work. Like I said, as a file it's sharp. It does well at removing material in a convex shape that's perfect for a fret crown. There are two sides to this file...medium and large. The differences appear to be how deep the concave file surface is. I would still recommend taping your fretboard to keep from scratching it. The file's surface that can touch the fretboard is smooth and not abrasive, however shavings will still get between the smooth edge (of the tool) and the fret board and create etches in the fret board. It won't go through tape though. I would also recommend using some fret rubbers (erasers) to polish the frets to a nice glass-like surface. This file does well at crowning, but it shouldn't be expected to create a polish. Doing a proper fret job requires a series of steps. This tool is perfect for one of those steps - crowning. All that said, I'm glad to have this on my bench. It'll get plenty of use. Highly recommended!

I delayed my review for awhile because i was still working with this product on a few fret dressing jobs. I had already contacted the owner and maker of this excellent tool and he was very responsive and loved the work I had done on a few of my guitars awhile back. I asked him for any possible future tools and handle grips and it seems like they have been in the works but are still on the drawing board! I'm looking forward to any new developments. Ok, this file was used on 3 guitars so far and here's the pro and cons +Excellent movement and versatility, This fixed one fret job where I had to do the fret level and crowning all over again, this file did an amazing job over the other one I used! It put it to shame +Frets were uniform after crowning. This thing evened out the fret ends as well which was a pleasant surprise and only needed to use the fret end file for touchup near the fret board! time saver +2 in 1 large and medium fret gauge 6100/6105 +Saved me Alot of time and energy +Perfect for beginners that are learning how to do Luthier work +Easy to clean +Really good grip, no damage to fret board or no sliding off when filing +Got more confidence in my repair work as a learning Luthier (I took this into a guitar shop and got complimented on the frets looked great, just a few minor uneven frets where not enough material was filed off +Longevity +Going off price listing for fret dressing at a local repair shop, I saved around $700-1000 in repairs. Cons: - Handle could be bigger for big hands. rubber coating for grip - Gums up so have a cleaning brush handy - Can be aggressive in taking alot of material off if not careful so keep that in mind considering this is a Higher quality fret file Overall, I LOVE! this tool and its something i will have on hand in my kit so whenever i get a guitar and it needs a setup, i can do it at the comfort of my home and i can get to playing on the same day! unless I really have to take it to the repair shop. STRONG RECCOMEND!

I have a fantastic luthier, but he's so good he's always busy, so wanted to learn to do some stuff myself. This fret dagger is a fantastic little investment. I tend to make flat spots pretty bad on my frets with my weird crippled left hand, so I often need to do a quick re-crown during a string change to take out some buzz. This fret dagger works great and makes it real fast. Tape it up, check which side to use, paint 'em with the marker, and crown 'em quick. Hit 'em with the sanding sponge and 000 steel wool, clean and lemon-oil the fingerboard and the thing plays wonderful again. I can do that a good 4-5 times before having to do a partial re-fret at the luthier. I've had it about 10 months now, used it a ton, very happy with it. I make sure to clean it good with a brush after every fret, and the teeth on the thing seem to be lasting quite well. At the price, I'm not too worried about the teeth lasting, it's a good investment for my use case. Absolutely recommend the thing. Just a great tool to have when you've got some buzzing flat spots. Fully awesome at crowning the full fret levels I've done as well.

Hace su trabajo bien para trabajos caseros, para trabajos de uso rudo está la versión diamantada, aún que con dos trabajos sacas para comprarte la versión mejorada, en conclusión es perfecta para mantenimiento a guitarras personales, pero no sé que tanto desgaste tenga al uso de un luthier profesional

Dagger 2.0 comes highly recommended and the price point vs the quality is spot on. Very ergonomic and manufactured to a very high standard, the diamond coating performed better than I expected. first use was on very old worn down frets, leveled so low they actually should have be replaced but I figured give it a go it can't hurt. The dagger did it's job perfectly and brought them back to life. The other neck with a just small level took all of 5 minutes to get a perfect crown all the way down. Highly recommend this crowning file.

First time using a fret crowing tool, made quick work of my worn-out frets (which I had to level down quite a bit) and the final results were very nice! Works well and leaves a nice finish easy to polish. Excellent results. The only issue I have is the price in Canada compared to US which is ridiculous, and just recently went up quite a bit too... If you're in USA don't even think about it, get it! If in Canada, well, you are just getting ripped-off as usual... not the product's fault. It is a very good tool that saves lots of time and provides fast quality results. Why are Canadian being ripped-off all the time?

Great file.

nice quality
