1. We tested various designs and jaws to find the ultimate angles for extraction. Our Precision Pullers are meticulously ground to our specifications. 2. The outer face is ground and polished to be flush with the fingerboard, and glide under the fret crown edge. 3. Inner jaw tips are ground to a 45-degree angle to gently nudge the fret free of its slot as the jaws close. By carefully exerting less force on the fret wire, the smoother action eliminates unwanted chipping, especially if you've loosened the glue a bit with a warm soldering iron. 4. When working with dry and difficult fretboards, use the Precision Pullers with our Chip Stoppers for an extra layer of confidence in a chip-free and hassle-free job. 5. Do not use pullers to cut fretwire-the custom ground jaws can be damaged if used for anything other than pulling. Precision Fret Puller Get ready for the smoothest fret removal ever!
