Developed by Australian violinist and pedagogue, Andrew Baker, with a simple goal in mind: Create rosin that allows players to be their best. The process was anything but simple, and involved study, exploration, discovery, and endless testing.

Leatherwood Rosin is formulated differently for each instrument, violin, viola, and cello, according to the physical characteristics of each. In addition, there are two recipes available for each: Crisp and Supple, which describe sound and feel of the rosin:

- Crisp: Emphasizes a sforzando attack, clear articulation, defined sautille bowing, and a precise and resonant sound

- Supple: Rounder attack, seamless bow changes, and a lush, warm sound.

Since the crisp and supple formulas became available, Andrew has customized blends of the two formulas for individual requests. The most popular mixtures are now readily available to Shar customers in 50/50 supple/crisp blends for each instruments, as well as 75/25 in 75%-supple or 75%-crisp blends.
