Felt Wear-Resistant Steel Piano Tuning Cloth Aluminum Alloy

A hand tool designed as a piano tuning cloth for keyhole felt work, combining a compact cylindrical form with a guard cap. As a trimming tool, it is made to shape and trim felt cleanly, helping create neat edges and accurate results during piano adjustment tasks. The shell is made of aluminum alloy with an imported high wear-resistant white steel for long-lasting, stable performance. It measures about 16 cm in overall length, 16 mm in diameter, and weighs approximately 76 g, making it easy to hold, control, and store. It supports exact trimming work and helps improve efficiency when working on detailed instrument felt areas.
