- ERGONOMIC TOP-DOWN CONTROL: SharkFin places your hand directly above the cutting action, allowing controlled downforce without using a death grip – reducing fatigue during repetitive fret crowning work & providing true 1:1 cutting feedback
- RELAXED UN-GRIP CUTTING STROKE: Designed so you can ease your grip during the cutting stroke & stay relaxed on the back stroke helping prevent hand pain, wrist, forearm strain & the cumulative fatigue that makes fret crowning feel like punishment; comfort you'll notice on the first fret & appreciate even more on the final fret
- D.I.A. CUTTING GEOMETRY FOR PRECISION CROWNS: Proprietary Dual Integrated Arc (D.I.A.) geometry delivers exceptional control & predictability as the crown narrows prevent you kissing the fret top so your freshly leveled frets stay intact while you dial in razor-thin centerlines
- CLEAN CUTS READY-TO-POLISH FINISH: Chatter-free cutting leaves smooth crowns with minimal file marks so you sand less, preserve the crown & arrive at sparkling frets faster. The SharkFin design also solves the challenge of working on your upper frets with plenty of clearance for the guitar body & toggle switch
- BUILT FOR SERIOUS BENCH TIME: Made from high-carbon, heat-treated European steel for long life - consistent performance on nickel-silver & stainless frets; rounded, contoured, beveled edges and corners help protect fretboards & guitar tops from deep scratches and gouges
- PROFESSIONAL LUTHIER TOOL: Designed for luthiers, guitar techs, builders, and serious players who demand more control, less fatigue, and tighter fret crowns with cleaner results during guitar maintenance and repair work
- VERSATILE SIZE OPTIONS: Available in MD, LG, XL and XXL sizes to accommodate different fret dimensions on both guitar and bass instruments, ensuring compatibility with various fret size requirements
