We have always paid special care and attention to rehairs because they are of paramount importance as the meeting point between bow and instrument.
For this reason I keep in my workshop different kind of hairs, such as Mongolia, Siberia, Blond and others, and I log every rehairs for having a “database”for each Bow that goes through my workbench.
This is the way to find the right rehairing that matches the demands of the musician and the characteristics of his instruments.
