Cutting string slots is delicate: if you cut one slot a little too low, you've blown the nut and have to start over. StewMac's own Don MacRostie devised the Safe Slot™ to make accurate nut slotting fast and fumble-free. He shows us how it's done in this video!

A trick the pros use:
Stack feeler gauges against the nut to set your slot depth. When the slotting saw touches the feeler gauges, you've hit your depth. The Safe Slot Nut Guard holds the feeler gauges tightly against the nut, and curved to the radius of your fingerboard. This leaves both your hands free to file. And you'll be able to work faster without worrying about cutting too deep.

  • Holds multiple feeler gauges
  • Pulls gauges tight to match fretboard radius
  • Locks in place against the nut. No slipping!

The pivoting caul adapts to most neck shapes, and the felt padding is guitar finish friendly. Use the clamp for any fingerboard up to 2-1/16" wide.

Also available with 11-piece feeler gauge set.
6" x 1/2" steel gauges include:
.016" .022" .028" .034"
.018" .024" .030" .040"
.020" .026" .032"

Amazingly simple

This tool makes the job so much easier.It takes the guess work out of how deep the slots should be. I highly recommend this tool! It's a must have!

Easy Slot

A great little tool. Much easier than trying to hold the feelers by hand. With the correct amount of tension applied the feelers conform exactly to the fret-board radius to give perfect depth slots.

Its a cool tool but...

Hi guys! I received the Safe Slot Nut Guard last week here in Portugal and already used it. Its a cool tool...shurely a helper, but the old japanese 70's acoustic I was fixing and making a new nut, had a the headstock in a deep angle, so the Nut Guard had to stay a little far from the nut. It helped me making me the new nut but I had to be carefull not to damage the fretboard with the file. Nevertheless im glad I bought it

Doesn't work with necks having a thumb crest

Many banjos have a knob or crest on the back side of the neck opposite the nut as a place to put one's thumb. The yoke of the safe slot does not work with such a design.

A helpful tool!

This tool was a real help in getting the initial radius and slot depths right, but I am not sure how effective it can be if you are trying to get some super-low nut action. I still proceeded without the guard when getting down to the final depth (0.012 - 0.010") is very low where every stroke counts. Maybe with a bit more experience and experimenting with this tool, it could be used to cut the slots that low and save a lot of time...we shall see.

Saved my nutz

This device has saved me from a lifetime of "Damn, I cut that slot too low" I am a perfectionist. Your Safe Slot Nut Guard has made me a little more perfect. Thanks a million, Dave "I'm a little surprised I didn't think of it first".

Never ruin another nut

The Safe Slot Nut Guard is a wonderful, easy-to-use tool for cutting the nut to the exact string height. Instructions walk you thru the procedure with ease and by the time you get to the 3rd groove, you'll be a pro. Especially with brass nuts, where mistakes get costly.

control your depth of cut??

After using this safe slot guard, one would wonder why you would try to proceed without it??? Super easy to use and greatly accurate. This will enable you to get the first fret to nut slot perfect, without the first fret string height perfect none of the rest of the fretboard will be correct. Save the grief get one!!!
