SharkFin Guitar Fret Crowning File | Professional Luthier Fret File | Top-Down Ergonomic Control | D.I.A. Geometry | Razor-Thin Crowns for Guitar & Bass | Pro-Pack (1 Handle+BOTH SIZE FILES)

ERGONOMIC TOP-DOWN CONTROL: This tool positions your hand directly above the cutting action, enabling controlled downforce without requiring a tight grip reducing fatigue during repetitive fret crowning tasks and delivering precise 1:1 cutting feedback.
RELAXED UN-GRIP CUTTING STROKE: Engineered to allow a looser grip during the cutting stroke while maintaining relaxation on the back stroke helping to prevent hand pain, wrist and forearm strain, and the cumulative fatigue that makes fret crowning feel like a chore; comfort you'll notice on the first fret and value even more on the final one. D. I. A.
CUTTING GEOMETRY FOR PRECISION CROWNS: Proprietary Dual Integrated Arc (D. I. A. ) geometry provides excellent control and predictability as the crown narrows preventing accidental contact with the fret top so your freshly leveled frets remain intact while you establish fine centerlines. CLEAN CUTS, READY-TO-POLISH
FINISH: Chatter-free cutting produces smooth crowns with minimal file marks so you sand less, preserve the crown shape, and achieve polished frets more quickly; the design also addresses the challenge of working on upper frets offering ample clearance for the guitar body and toggle switch.
BUILT FOR SERIOUS BENCH TIME: Constructed from high-carbon, heat-treated European steel for lasting use consistent performance on nickel-silver and stainless steel frets; rounded, contoured, and beveled edges and corners help safeguard fretboards and guitar tops from deep scratches and gouges
