Review: Great invention. Totally worth it! - 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!
Review: Versatile! - 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!

## Features

- The Dagger’s exclusive D.I.A. (Dual Integrated Arc) design gives you greater cutting control, perfect fret centerlines and a finer fret finish.
- Prevent Damage to Your Frets and Fretboard - with the Dagger’s 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 there’s 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 FretGuru’s 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!

## Questions & Answers

**Q: Will this tool work for stainless steel frets?**
A: Yes. It will just take more elbow grease on your end, and wear out the tool faster

**Q: Will it work on low narrow frets on mandolins**
A: Hello Richard,

Depending on how narrow your mandolin frets are, this may not be the ideal file for that application. 

Do you know how wide the frets actually are? 

The sweet spot for the narrow side of this file is around .080" to .095" + or so.

The good news is we have a smaller version of this file in the works.

**Q: How long should it last?  I've used my 2.0 on about 25-50 necks and it seems dull.**
A: 25 to 50 necks? Then It paid for itself eons ago. I've only done 2 necks so far. If it's like my other files then it should last a lifetime. That is, if you keep it clean at all times with a brass brush and chalk. And store it in a dry place. Hope I get 50 necks out it. I'll be doin a stainless fret job soon. True test on that one,

**Q: Is it faster to use expedited shipping? Does it come with tracking number?**
A: Yes, if you order the "Seller fulfilled" version (will say Ships from FretGuru / Sold by FretGuru, NOT "Ships from Amazon") and select Expedited, I can personally package it now and get it out the door today (Saturday).

You'll get the tracking number.

Thanks!

### ⭐⭐⭐⭐⭐ It's super easy to use, huge difference
*by P***L on December 12, 2022*

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.
