Founded in 1890 in London by F. Hider, Hidersine is a British maker of orchestral string instruments and accessories best known for its rosins, which trace back to a formula developed in 1877 by a Swiss scientist and violinist. The company expanded its rosin catalog with the addition of Amy Birch's 'AB' Rosin in the 1970s and W.E. Hill & Sons rosins in the 1980s, and its lineup now includes lines such as the Reserve 21, Deluxe, and the numbered 1V/3V student rosins for violin, viola, cello, and double bass.

Beyond rosin, Hidersine produces a tiered range of student and intermediate orchestral string instruments, including the entry-level Vivente outfit favored by the European String Teachers Association, the Piacenza intermediate outfit, the Veracini outfit aimed at degree-level students, and the Guarneri-pattern Melodioso violin. The company also supplies bows, bridges, mutes, shoulder rests, cases, strings, and pitch pipes for the bowed-instrument market.

Distributed through Barnes & Mullins in Oswestry, Shropshire, Hidersine is widely stocked by string-instrument retailers and music education suppliers across the UK and internationally, with a particular foothold in the school and conservatoire student market.

Hidersine has 2 products cataloged on Equipboard, including Cellos and Rosin.
