Color: Dagger 2.0


Features

  • Faster Cut, Smoother Finish - The Daggers exclusive D.I.A. (Dual Integrated Arc) design gives you greater cutting control, perfect fret centerlines and a finer fret finish. Its sharp enough to quickly bring the sides of the fret up to a clearly defined center, without worrying about accidentally taking too much off the top. Some of our customers have even called it foolproof.
  • Prevent Damage to Your Frets and Fretboard - with the Daggers exclusive smooth beveled, contoured edges. The angled cutting surfaces and ergonomic handle are balanced and comfortable, helping to reduce hand fatigue, and also preventing damage to your guitar body by allowing maximum file and finger clearance over the guitar body, switches and pots as you move up your guitar neck. In most cases theres no need to mask off your fingerboard.
  • Avoid School Bus Roof Shaped Frets and Their Tone Destroying Effects - Precisely leveled and crowned frets are the very foundation of a great sounding guitar. Worn, grooved, flattened frets will rob you of tone, volume, while doing a number on intonation. Our professional grade crowning file was created with file masters in the heart of Europe to fix these issues. Made from high carbon European tool steel with razor-sharp teeth to deliver a clean, ready-to-be-polished cut every time.
  • Designed For Most Guitars - This dual-sided fret crowning file is the ideal size and shape for acoustic and vintage electric guitars (MD or LG side), as well as modern electric guitars, or those with jumbo and super jumbo frets (LG or XL side), up to about 110-112 wide maximum (aka Dunlop 6100). For huge monster frets, we have a Mega version of the Dagger 2.0 file coming soon. Use with FretGurus Precision Fret Leveling Beam for best performance.
  • For Professional Luthiers, Guitar Techs, Hobbyists and Beginners - The Dagger file is precise, advanced and durable enough to satisfy the most demanding professional luthier, yet so comfortable, easy and intuitive to use that even a first-time beginner can get superb results. Regular fret crowning, repair, maintenance and polishing has never been more comfortable, fast and easy. BEWARE of Dagger Shaped Fakes when buying!

    • Does very well for the price paid.
Color: Dagger 2.0
The file works better than the typical cheap-O Gurian fret file. Cuts smoother, leaves less file markings, feels like it has more control and more cutting surface. However, I still prefer my Z-file. There is much less worry about removing the top of the fret and it leaves a smoother finish. It is not a truly fair comparison because the Z-file is a diamond file and more than 2 times the price so I would expect it to do the job better. The downside to the Z-file is that it costs a ton and won’t do jumbo frets. I don’t care what anyone says. Anything more than a standard medium fret size and the Z-file is a no go. This will cover all fret sizes and do a decent job which is a major bonus for someone who only wants one file. For what you pay, this is probably the best deal in a fret file that I have found. I may give the Fret Guru diamond file a shot and see if I like it better but I am going to have to start seeing more jumbo fretted instruments before doing so. For now, this file will work for what I need. ... show more

    • Diamond Dagger vs Dagger 2.0 (Which is better?)
Color: Diamond Dagger
Review Image by Philosopher Rob Philosopher Rob
Review Image by Philosopher Rob Philosopher Rob
I bought both FretGuru files (Diamond Dagger and Dagger 2.0) through amazon and so this review will be a comparison of the two. Short Version: They are both excellent; but if you can only get one, the Diamond Dagger is better in my opinion. Read on for more information. I’ve been playing guitar for over 30 years, but only began to work on my guitars seriously in the last 5 years or so. I’m not a professional guitar shop guy. I am writing this review to help other hobbyists like me. I’ve leveled, crowned, and polished several guitars. One file I have used to use for crowning was the StewMac Diamond Compact Z-File original file (300 grit). It is a great file, but as StewMac says it is: “ideal for worn, low, and wide frets.” Because I like to use jumbo frets (Dunlop 6100, and Jescar FW57110), I decided to take a chance on the FretGuru Dagger 2.0 because it has two sides: (1) one made for Dunlop 6100 frets and (2) one made for Dunlop 6105 frets. The Jescar FW57110 frets happen to be very close in dimensions to Dunlop 6100 frets. I crowned one of my guitars with the Diamond Dagger (Jescar frets, nickel silver) and another guitar with the Dagger 2.0 (Dunlop 6100 frets, nickel silver). Here is what I experienced. The Dagger 2.0 works well. It cuts smoothly and feels good in your hand. However, it only cuts one direction and so after every push forward you have to lift it off the fret and start again. After crowing a fret I would clean the Dagger 2.0 with a brass wire brush to unclog it of any stray pieces of metal. That worked pretty well, but made it more labor intensive than the Diamond file, which did not need such cleaning. Sometimes there was a stubborn piece of metal in the file that I would pick out carefully with an ”icepick” like tool looking through my magnification visor. All in all, the Dagger 2.0 performed very well on that guitar and the frets polished up nicely with my Dremel tool and polishing rouge. I tried the Diamond dagger on another guitar and it also worked very well, but was better overall for three reasons. First, Diamond files are great because you can “saw” back and forth without lifting it off the fret (though make sure not to take off too much—you have to leave a thin magic marker line so the fret leveling is not undone). Second, I did not have to clean the Diamond version with a brass wire brush. Occasionally, I’d clean it with nylon bristles, though to be honest, I don’t think it needed such cleaning. The Diamond cuts nickel silver frets like butter. Third, the Diamond dagger has one feature the Dagger 2.0 does not have. The Diamond Dagger has 2 extra filing sides on the opposite end of the file (you have to see the pictures to understand what I mean). But this is great because sometimes I find that when crowning a fret my magic marker line in the middle of the fret is fatter/wider than at the ends of the fret. With the shorter filing side of the Diamond Dagger, I can work on just that middle section to make it have as thin a line as the other parts of the fret. This is really a great feature in my opinion and ergonomically both ends of the Diamond Dagger feel great in your hand (very comfortable and easy to maneuver). So, in conclusion, if you are working on Dunlop 6100/Jescar FW57110 frets the Diamond Dagger fits them like “hand to glove” and gives great results--even to hobbyists like me. The quality of both files is great, the prices are better than competitors; plus Bernie (the Fretguru owner) is a nice guy and very responsive to email. I emailed him with a question and needing some help and replied the same day. Finally, StewMac is great too; I love their products and customer service—but as many know they do have higher prices. All of that said, while StewMac’s Diamond Compact Z-File centered file will not work with jumbo frets, they do have other files that will (#4491, #5054, # 5183). I like both companies, but when it comes to my jumbo frets, the FretGuru Diamond Dagger is my new file of choice. Hope this was helpful for some of you. ... show more

    • Great invention. Totally worth it!
Color: Dagger 2.0
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! ... show more

    • Best Crowning Fret File I own
Color: Dagger 2.0
I own several different crowning files from the cheap $10 ones to the expense $100 ones. This one is the best one I have. I bought it a few months ago and finally used it last night. Not only was this the best crowning job I have done to date but it was also the fastest and most accurate one too. The tool has a very nice balance and easy to control. I am right handed but often tend to switch hands when doing repetitive jobs such as fret work and because of the balance, switching to my non-dominate hand was very easy. Its so easy to control its very easy to take just the right amount of matter off of each fret. I had two complaints. Neither are a big deal though. First, it seems the file gums up easy so keep a bristle brush near by to clean it. Second, I wish the handle had a rubber cover of some sort over it. That would make it even more comfortable to use BUT I have used worse crowning files. Over all I am very pleased and will buy more of these in the future if needed. I wish I had the option off giving 4.5 out of 5 stars. ... show more

Once the frets are leveled, this little tool does a superb job cleaning up the edges, equally on each side. Polish up afterwards and DONE. Good bang for your buck, made with quality and craftsmanship.
