Grobet Tuning File

Grobet USA, Made in Italy, Swiss pattern file.

0-Cut is right on the margin between coarse and fine. It's perfect for removing brass with a light touch. It's coarse enough to have power but doesn't leave scratches and tracks on the reed.

Warding shape: Like a flat triangle with teeth on every side.

Raise or lower the pitch of a reed with the reed plate on or off the comb.

This file works on Brass, Stainless Steel and Phosphor Bronze reeds.

Tune the blow reeds without taking them off the comb.
