Nut and Saddle Shaping Files, Set of 2

Two files, four cutting surfaces! Refined in our own shops for smoother, easier nut and saddle shaping.

This pair of specialty files is ideal for roughing-in and fine-shaping the delicate contours of string nuts and acoustic bridge saddles. Using the files in combination, you can quickly refine a rough-cut nut to a smooth shape, ready for final polishing. The narrow cutting width makes it easier to round the top of a nut or bridge saddle more smoothly and accurately.

Each steel file is 10" (254.00mm) long with a rubber-coated handle for comfort, and has two different 5-3/4" x 1/4" (146.05mm x 6.35mm) cutting surfaces. That's four cuts in all: Coarse, Medium, Fine, and Extra Fine. The narrow 1/8" (3.18mm) edges are smooth.

Both Nut and Saddle Shaping 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.

Excellent files!

(Customer's Reviews)

These files have made the processes of nut and saddle making enjoyable. Another great tools from Stewmac!


Solid, versatile files

(Customer's Reviews)

So far, I've used these files to shape a TUSQ XL nut as well as doing some shaping on an LP's control cavity cover. I will soon be using them to help in rough-shaping a neck after rasping. The files have held up very well to the work I've used them for so far, and I expect that they will be sticking around for quite a while. A very worthwhile investment for my collection of tools.


Really Smooth Action! These files are excellent!

(Customer's Reviews)

These files are a joy to use. The action is very smooth when shaping bone. Rounding over the headstock side of the nut took no time at all with these, and the finer cut files really did smooth out the flat spots before final sanding/polishing. I also used them to widen and square up a poorly made nut slot (where the nut actually sits), but for that job, it would be better if the edges of the file were ground down a bit to make the edges a bit more square so the edges of the teeth wont dig in to the nut's perch so much.
