## Description

We’ve completely re-engineered the original, highest rated, best selling FretGuru file, resulting in an unbelievable performance improvement.At the heart of the new file is FretGuru’s exclusive D.I.A. (Dual Integrated Arc) cutting geometry, which gives you far more precise CUTTING CONTROL, ACCURACY and FINISH than any other file - especially diamond files - GUARANTEED.There's an ideal-yet-elusive "HOLY GRAIL" for the way a fret crowning file SHOULD cut, where the file never touches the center line or "peak" of the fret top until the last few file strokes.Especially true with freshly leveled frets, as you don't want to disturb the perfectly level "plane" you've just created by removing material from the fret tops with a crowning file. Ideally you want to leave the finest sliver of leveled fret along the centerline, which is then polished.Diamond files are often guilty of this - with the random way diamond grains are applied to the cutting groove, the stray grains often stick up higher than the surrounding grit.How did we do it? I've wrestled 5 years with how to create this, with machinists and toolmakers just scratching their heads when I told them what I was trying to do.The first problem with every other fret crowning file, they are all made using standard off-the-shelf tooling - typically ball end mills - which are only available in standard size increments, and MORE IMPORTANTLY, only available as a perfect sphere shape.But one day the "lightbulb" went off, and I ran this idea by one of the top CNC toolmakers in the country.He still didn't think it would work, but reluctantly agreed to make a prototype tool... with no guarantee, that would cost more than 2 years supply of our normal tools.The results? Mind-blowing, better than I could have ever imagined!But don’t take my word for it, read the rave reviews from experienced world-class luthiers, AND absolute beginners. Then try it for yourself.

Review: 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
Review: 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.

## Features

- Faster Cut, Smoother Finish - The Dagger’s exclusive D.I.A. (Dual Integrated Arc) design gives you greater cutting control, perfect fret centerlines and a finer fret finish. It’s 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 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 intotion. Our professiol 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, maintece 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!
