    I'm willing to spend money to get the best tools for the job.

    I'm tuning F#BEAD on a 35" 5-string so I will be going with .190 .142 .106 .079 .055

    I would also like to tune the other nut slots appropriately.

    At the hardware store, look for Chain Saw Files, used for sharpening the teeth on chain saws. One of the sizes is 1/8", which is right about at 0.125". It's a straight round file, crossed double-cut teeth, very smooth cutting, inexpensive. They also have 3/16", 0.188".

    That does seem appropriate, for some reason. :smug:

    I use a 'diamond needle file' which has at least one side gently curved. Smoother and more effective abrasion and usable for all slots so you don't need a file per slot, file each slot wall back separately, acheiving slot roundness by eye.
    You can get diamond chainsaw files.
