It is aimed at professional luthiers, guitar techs and serious hobbyists who need faster cutting and a smoother finish compared with traditional three-corner files. The D.I.A. dual integrated arc design gives controlled cutting so the sides of the fret are raised to a defined center without over-cutting the top, which makes it especially useful when consistent fret geometry and tone preservation matter.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eDual Integrated Arc design:\u003c\/strong\u003e Provides controlled cutting and helps produce perfect fret centerlines for consistent crowning across an entire neck.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eDual-sided blades (MD and LG\/XL):\u003c\/strong\u003e Covers a wide range of fret widths from about 0.080 in to 0.110 in so one tool fits most acoustic, vintage and modern electrics.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eHigh carbon European tool steel:\u003c\/strong\u003e Razor-sharp teeth deliver a clean cut that reduces polishing time and yields a smoother finish right off the file.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eBeveled, contoured edges:\u003c\/strong\u003e Smooth edges and ergonomic balance reduce hand fatigue and minimize danger to the fingerboard and guitar body while working.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFaster material removal:\u003c\/strong\u003e The aggressive Dagger profile brings fret sides up quickly so jobs finish faster than with traditional three-corner files.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Dagger 2.0 is ideal for professional luthiers and guitar techs who need a reliable, repeatable crowning tool that speeds workflow and reduces polishing time.
