FRTLZR® BlackEdge Notched Straight Edge - Made in Germany
The FRTLZR Blackedge Notched Straight Edge is a precision reference tool designed for accurate evaluation of guitar neck and fretboard geometry. CNC-machined in Germany and finished with a matte black anodized surface, it combines workshop-grade accuracy with a clean, reduced aesthetic—accented by a discreet, centered logo.
Unlike standard straight edges, the Blackedge features precision-cut notches that bypass the frets and rest directly on the fretboard surface. This allows true measurement of neck relief and fretboard straightness without distortion from fret height, wear, or inconsistencies. The result is reliable data for precise adjustments, diagnostics, and professional fretwork.
Developed for luthiers, guitar technicians, and detail-oriented players, the Blackedge serves as a dependable geometric reference throughout setup, repair, and construction processes.
Key Features & Benefits
CNC Precision Made in Germany
Manufactured to tight tolerances with consistent surface quality, ensuring dependable accuracy in professional workshop environments.
Notched Design for Fretboard-True Measurement
Precision-engineered notches bypass the frets, enabling direct assessment of the fretboard itself—essential for correct truss rod adjustment, fretboard leveling, and diagnostic work.
Multi-Scale Compatibility
Designed for accurate referencing across the most common electric and steel-string acoustic guitar scale lengths:
25.5"
25.0"
24.9"
24.75"
Matte Black Anodized Finish
Durable, scratch-resistant surface with reduced glare, improving visibility and edge definition under workshop lighting.
Visibility-Enhancing Chamfers
Finely chamfered edges increase edge readability and make contact points easier to identify during inspection and setup.
Clean, Functional Design
A slim, modern form that prioritizes usability, balance, and visual clarity without unnecessary elements.
Wall-Mountable Storage
Integrated mounting options allow for secure storage and clean presentation in workshops or studios.
Applications
Neck Relief Evaluation
Accurately measures neck relief by referencing the fretboard directly, enabling precise truss rod adjustments.Pre-Fretwork Diagnostics
Identifies twists, humps, uneven areas, and ski-jumps before leveling, refretting, or planing.Fretboard Leveling & Planing Reference
Provides a true straight reference for sanding and machining operations during repair or construction.Post-Fretwork Verification
Confirms correct neck and fretboard geometry after fret leveling or refretting, before final setup.Setup Baseline Establishment
Creates a reliable geometric baseline prior to nut, bridge, and action adjustments.Flatness & Parallelism Checks
Verifies flatness and alignment of necks, fretboards, and other precision components.
Technical Specifications (Summary)
Manufacturing: CNC-milled in Germany
Finish: Matte black anodized
Design: Precision notched straight edge with chamfered edges
Scale Lengths: 25.5", 25.0", 24.9", 24.75"
Storage: Wall-mountable
