Double-edge Nut Files

A nice addition to the toolbox, especially good for basses. Marked sizes would be nice, but two minutes with a Sharpie and its done.

good tools but I too would like to see them more clearly labeled, have more useful sheaths and include a .010 and .015 to use on mandolins.

These are 1000x's better than the straight files that get stuck in the slot !!!! Because there are files on the sides and it is tapered, it smoothly cuts the slot in a V shape without gettig stuck. I've given them a 5 star even though I've only used them once.

Work excellent, even on man-made products.

These do a fantasic job. They are solid, easy to handle, and effortless to cut through bone, plastic, or graphite. Definitley a good investment. Only problem is that I would like to see them make a mark on which side is which... very small files should have that indicator. Latest build... a '51 nocaster. Oh you see the string tree and say WHAT? ? ? It's been replaced with the original button style. And decaled also! 7 degree radius.

The files are excellent tools.
one remark: they are delicate tools, so best to store them in a sturdy box.
The plastic protection sleeves that are included are a pain to use. They stick to the tool when inserting or taking out the file

These files do a very good job..But the labels should be more informitive as to which side is which..
I would also like to see a .010 size..The .012 is too big for the first string on some guitars..

I bought quite a few tools recently so I can do neck jobs instead of taking them to some else. I've gotten proficient at setting up the necks with the nut files, relief gauge and nut string height gauge and fret crownig files. My guitar actions are now awesome and a joy to play. I'm on my way to becoming an outstanding luthier.

I have not had good luck with these files the last two times they were ordered. Some of the files are very dull and do not cut very well. Some of my older files actually cut just as well.

These work well and are a big improvement on trying to do the job with needle files. They produce a V shaped slot with a rounded seating for the strings. I also have the single edged files which have a better profile, I think, giving vertical sides and round seating. However the double edged are easier to use but I agree with the other reviews the marking on the handle needs to be clearer and it is easy to use the wrong file. I found matching the gauge file with the string gauge for both types of file gave a tight fit and a bit of rocking is in order to loosen a bit.
