Independent shopping perspective

The Korena take

For acoustic-guitar neck adjustments made through the sound hole, this 5mm GrooveTech wrench provides a purpose-built alternative to a standard hex key. Its blade is proportioned to enter the sound-hole opening and reach deeply recessed truss rod nuts, including ones located beyond bracing. The ball-end tip helps the tool seat in the nut, while the oversized screwdriver-style handle gives you a controlled grip when making the adjustment. The 5mm version is primarily intended for Martin guitars.
