The set contains the five most popular radii and is made from hardwood sized for use with Stikit abrasives, so the single biggest reason to buy is accuracy and consistency when working through common guitar fretboard curvatures.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFive popular radii included:\u003c\/strong\u003e The set contains 7.25in, 9.5in, 10in, 12in and 16in blocks so builders can match most vintage and modern fretboard curvatures without guesswork.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8in length:\u003c\/strong\u003e At 8in (203.20mm) long these blocks span the scale length area typically worked on and help maintain an even curve while sanding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardwood construction:\u003c\/strong\u003e Solid wooden blocks offer a stable sanding surface that resists bending and keeps the radius true under pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesigned for Stikit abrasives:\u003c\/strong\u003e These blocks are sized to work with stick-on sandpaper for quick setup and consistent material removal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual use for fretwork:\u003c\/strong\u003e Use coarse grits (80-220) to shape a fingerboard and finer grits (220-400) to level and dress frets, so one kit covers both jobs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis set is aimed at guitar builders, repair techs and experienced hobbyists who need repeatable radii for fretboard shaping and fret leveling.
