What other tools of the band instrument repair trade have received U.S. patents?

The MDRS was actually awarded 2 separate patents: 1 for the concept of the tooling assemble and 1 for the concept of marketing the tools as a shop setup/kit. During the process of our patent application we found the 2 other BIR tools that have received patents: The Ferree’s mouthpiece puller, and the Ferrees Concept wood and metal dent balls.
