Let customers speak for us
from 92 reviewsI’ve used this tool numerous times with great results. It’s paid for itself many times over.
Perfect fit, quick shipping, would recommend
High quality, accurate luthiery tools. I will definitely order more.
Extremely well built! Makes radiusing the fretboard quick, simple and most importantly, accurate. It immediately became a "must have". Combine this with the sanding blocks and you are on your way!
I used it a few times, really good for grading the radius that's required. Good tool to have.
Works as it should. Makes radiusing a fret board much faster than sanding.
Great product that gets the job done well
Pretty great idea. Whish more 3D printed products were available.
Always find the best engineered, creative from small companies.
This works out good.
