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!

    • 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

    • Works as advertised. Great tool.
Color: Dagger 2.0 XXL
Quality made, easy to use, works great. I love Stew Mac, but no need to pay twice as much for a Z file when this does just as well. It'll be a mainstay on my workbench from now on.

    • Great tool!
Color: Dagger 2.0
This was my first time using a crowning file, but I was very pleased with how well this file works. Files quickly and smoothly. Not a lot of polishing was required after filing and the smooth edges keeps the file from damaging the frett board.

    • 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

Review Image by John D John D

I recently did a side-by-side test of 6 different diamond fret files. The results weren't what I expected, but very eye-opening. I've used the StewMac Original Z-file for over 5 year, had a love/hate relationship with it until recently. The hate has really been shared with all fret files, and that is due to the cutting surface plugging up with fret filing debris, more on that later. Curiosity of a new file on the market sparked a shootout test of sorts between the StewMac Original Z-file, Music Nomad S-file, FretGuru Diamond Dagger 2.0, Baroque Gen 4, StewMac Compact Centered Z, and an Offset File sold by Bitterroot Guitar. I tested all files on a special built fake neck consisting 6 groups of 2 nickel and 2 stainless fret pairs. Each file was given a number and a place on the board. The board was flat leveled to have +/- 0.045" flat crown on all frets. Each file ran through a basic crowning test twice with the frets re-leveled between each test. This initial testing was to determine if the files would plug-up evenly, if any one would scar the frets more than any other, and just to get a feeling for the ergonomics and user input required by each file. In general, all files worked well, each did have its own slight needs, and only one was rather irritating to use. The frets leveled again (and again...), the testing continued but using a cutting lubricant. A drop or two added to either the diamond coating, or the fretwire, and all files worked better*, none plugged up and only needed a wipe of a paper towel and reapplication of a drop of oil to continue. A huge improvement for all files. *One thing to note, while adding the oil keeps all filing debris suspended and easily wiped away. I felt the addition of oil also reduced the aggressiveness of the file cut slightly. So, perhaps a few extra passed are needed when using cutting lubricant, but no file cleaning is needed. I'm expecting to see extended file life when using cutting fluid, but more testing will be required. Additional rounds of testing were done and the winning spot was very difficult to judge. All files used will do the job, they are all one step in front or behind then next file, with one exception. I truly hated using the SM Compact Z file. I have since sent it back for a refund. The Baroque G4 works well, is very affordable, but I found it to be a bit large for many tasks. The Offset file required the edges to be smoothed before it could be used. It would bleed you, not good! Otherwise it is a good file. The Music Nomad S-file was my expected winner, but after using it, I have come to see it as a rough-work file, not a finish file. It is designed to leave a coarse cut +/- 1/32" wide crown, and that is what it does. I need to follow this file with another file, one of my top 2 from this test. The top spot is shared by 2 different style and approach files. The FretGuru Diamond Dagger 2.0, and the StewMac Original Z-file. Both are very good files, and each requires a different user approach, but both can deliver the "hairline" crown that we strive for. My take away, any of the files tested can get the job done, mostly. My expected favorite is not what I expected, nor my favorite. The FretGuru truly surprised me in fit, feel and function. If I'm not using the SM Orig-Z, I'm using the FretGuru DD 2. If I use the Music Nomad S, I will be following it with the SM or FretGuru. Whatever file you get, it will likely get the job done, but some files make the job easier. The FretGuru DD 2, is right in there getting the work done! ... show more

It’s superior to my other two fret files in every way - ease and comfort of use - and the final outcome. Nicely crowned frets every time!
