Create an accurate radius quickly and without guesswork.
We make these hardwood blocks for use with Stikit Abrasives, to radius a fretboard quickly, accurately and without guesswork.

Shaping fingerboards: use 80 through 220-grit
Leveling frets: use 220 through 400-grit

Set includes the 5 most popular fretboard radii used in guitar building and repair:
7.25", 9.5", 10", 12", 16"

When working on compound radius fretboards, simply change blocks as you progress along the neck.

These 4" blocks are used for spot leveling, and can also be used as a radiused clamping caul when gluing frets. The longer 8" blocks are better for consistent, full-fingerboard radius leveling.

Dimensions: 4" (101.60mm) long x 2-3/4" (69.85mm) wide

What's your radius?
Quickly find the curvature of a fingerboard or bridge with a set of radius gauges. Use them frequently to check your work as you smooth or shape a fingerboard or frets: a quick visual check keeps you from accidentally altering the shape—a mistake that's easy to make and hard to fix.

Perfectly crafted...

I made this gift to my luthier since he lost a previous set. Wish they had a lacquer finish or some sort of protection to the wood... nothing you couldn't do yourself.

Exactly as advertised

Excellent to hold, won't slip. I bought the 4" because I like to take time with my guitars I don't like to rush them.

Essential tools for sanding fingerboards and leveling frets. Used them on a compound radius fingerbord, and it turned out great.

Stop making it so easy!

Good lord! I'll be out of a job if you keep selling these! Wonderful product. Makes my life/job so much easier I "almost" feel guilty telling my customers how much "hard" work I had to do on their necks/frets.

Works Great

Works great for quick leveling and radiusing of frets. Saves a lot of time and guess work when using straight blocks for the same application. Pictured is an ibanez 12 string in for a fret leveling. -Matt Dreher

4" Radius Blocks

I love these radius blocks. There small enough to go over the higher frets where you need 'fall off'.
