What Stands Out
Ergonomic Design
The top-down ergonomic control ensures comfortable handling, allowing luthiers to work efficiently and reduce hand fatigue while crowning frets.
Precision Crowning
With razor-thin crowns, this file offers exceptional accuracy in fret crowning, resulting in improved playability and tone quality for both guitar and bass.
Versatile Sizing
Available in medium, large, and extra-large sizes, the fretguru sharkfin caters to various fret sizes, making it a go-to tool for all luthiers.
Product Details
- 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

FretGuru Tools Editorial Review
The FretGuru Fret Crowning File is a highly rated, diamond dagger fret crowning tool that is suitable for use on electric, acoustic, and bass guitars with medium, large, or extra-large frets. Customers have praised its precision, ease of use, and value for money. The file is directional and works in the "push" direction. Customers recommend using a fine wire brush to keep the teeth clean. The file lasts a lifetime if it is cleaned and stored in a dry place. However, customers have noted that it takes more elbow grease to use on stainless steel frets, and the diamond coating may wear off after several uses.
