Nut Files.

I'm cutting a new nut for a new neck for a new project. It won't be boogered until after I'm done.

I'm doing this for my own amusement. I have a ton of parts laying around so I'm gonna burn up a few. I've always shied away from filing nuts but in this case I DGAF.

But having the proper files would be helpful.

 
I like the double-sided StewMac files with the red handles and the black handle tips. Those handles are very comfortable, big enough to get good grip, small enough to not get in the way. AKA very easy to control motion (very important).

YOU'RE a nut file.

 
initial cutting the groove (it is about equivalent to a Hi E 10), the fish file cuts to center, nice V cut~

These are okay, flimsy as the width gets skinny. nice U shape cut, consistent~

These have been around forever, the file taper can be a lil goofy. Getting use to them can be a somewhat of a challenge to get the right cut.~

A set of diamond jeweler files will put the final trim on the slot to a T~

I use all four items listed above.

 
If you want to DIY in pure cheapskate fashion, try starting the slots (already marked for string spacing and depth) using the narrow cutter harvested from an aluminum foil box (you might be surprised at how sharp and tough these are) and grafted into a thin piece of scrap wood. Then use the files from a set of welding torch tip cleaners (about $3) to widen/deepen the slots and to set the break angle. Pure ghetto, but it works.

Wow! Thanks for all the tips and links (and comic relief).

I'm currently leaning toward the StewMac or Hosco double-sided files. I love the more cost-effective ideas, but the caveman in me knows the lesser quality stuff doesn't stand a chance. I should probably pick up a spare nut........

ETA: In his typically awesome fashion, Mr. Steve Haynie kindly offered to send me his set of StewMac files to use. While it's an incredibly generous offer, the one thing I've learned from my inlaws is that you never - EVER - borrow (or loan out) tools.  But Thanks, Steve! You're what makes the HFC a great place to hang out.

I agree with Murkat and Jeff R, we always have an assortment depending on the job. I like the StewMac U shaped that are sized for the string gauge on electric guitars, and the Hiroshima files for acoustics. The .010" gauge file is very flimsy and easily broken, use 2 hands. X-Acto has a small back saw that I use to start the slots. 

The most important part is not how you cut the slot, but cutting the correct angle, not gouging your peg head in the process, getting the spacing correct, and then not cutting a slot too low else you will be starting over.
