Salchow and Sons is one of the preeminent shops in the world devoted to fine bows for stringed instruments. Founded by William Salchow in 1960, the shop is now run by Isaac Salchow, whose expertise, repair work, and bows are sought by dealers and musicians everywhere.

William Salchow began making rosin in his shop nearly 50 years ago. Not much has changed in the making of Salchow rosin since then; the recipe remains the same but the reputation has grown.
