Details

The most durable and efficient nut-slotting files available. Specially designed for nut slotting, each file cuts two different width slots.

Each 9/16" x 7-5/8" (14.29mm x 193.67mm) steel file cuts on the edges only, and tapers from the center to a different thickness on each cutting edge. The set of six files does the work of twelve!

Rubber-coated handles give firm, comfortable control for the job. The complete set includes edge widths for filing round-bottom nut slots on most stringed instruments, including basses. Each file's cutting edge is approximately 3-7/8" (98.43mm) long.

What files do I need?
Choose nut slotting files that are the same size or no more that a few thousands larger than your individual string gauges. A smaller file can also be rocked side-to-side to widen a slot to the desired size. For example, you can cut a .043" slot with a .042" file by moving it around a bit.

The most popular Double-edge Nut Files are included in the Essential Nut Making Tool Kit, which has all the basic tools you'll need for shaping, string-spacing, slotting and fitting string nuts like a pro.

Tip: Customize your files
We recommend that you mark on each side of your files so while working you can quickly tell the different gauge of cut.

Here's how: make a cut on a scrap piece of bone or wood with both sides of the nut file, then measure the width of each cut with feeler gauges to determine which side is which. Guitar strings of known gauges will also work as measuring tools in a pinch.

Once you have determined the proper edge, mark the file accordingly with a permanent marker.

good files, ok deal

By nicola from ct
(Customer's Reviews) Sunday, January 02, 2011


These files work very well but like all files of this shape ie: knife files they will bind when filing some materials, especially soft metals like copper. Good technique will cure this problem. All in all a good deal. I feel like these files could be a little less expensive

Need ID Marks

By Old Tucson Jack from Seward, NE

I have items 4542 and 4543 and like them but have a hard time deciding which side goes with which size. They need arrows or something to show you which is which.

Good but with a couple of issues

By Michael Bush from Greenwood, NE
(Customer's Reviews) Wednesday, December 22, 2010


My first issue is they are not well marked as to which edge is which, so I spend some time examining them to make sure I have the wider or skinnier one. There is probably a pattern to the marking on the handle and the file, but I'm not sure what it is. If they stamped the numbers over one another there would be no ambiguity.


The other issue is the taper. It works fine on any six string nut or on a twelve string with a bone nut or a graphite or softer plastic nut but with really hard plastic on a 12 it will crack the nut sometimes because of the taper getting in a slight bind. These are a great way, however, to get a full set of files. I really didn't need the bass sized ones though, and would have been happier to buy a set without those and saved some money.

The nearly perfect tool for the job

These files work great!

The one nit I have is that each size needs to be labeled individually.

This would make them more convenient.

Nice Files

By Colt W. Knight from South Charleston, WV 25309

These are nice files, but they do have a few draw backs.


If they are slightly bent, they don't work as well. Since they are pretty hard, you don't want to try to bend them straight, they will snap.


Rust very easily, so keep em up and dry. Nothing worse than rusty files.


When the saws are new, make sure to take a marker and designate which side is what size. After some use the numbers wear off, and it gets tougher to distinguish which side is larger than the other.

Just the best nut files available.

By Philippe from Ibiza, Spain

This set of nut files is just the best set of nut files available.

You don't need to look for any equivalent anywhere else, you'll never find it.



I recently used those in the making of handmade compensated "teflon saturated duroplast" nuts (the hardest and most slippery plastic available). I simply have to make them from scratch because companies such as GraphTech don't sell compensated nuts, and because the Earvana nuts are just way too absurdly overpriced for what they really are.



The price is still a bit high for a set of files, but these files are really special : they have round edges and they fit the string gauges used for guitars and basses. This means that they are pretty useless for 99,99% of any other handwork involving the use of files. And this also means that they are not produced and sold in "Industrial quantities", and therefore the costs of production of these files must be hard to amortize.



You need to work with nuts on a regular basis ... you need these files.
