The Evans Utility Tuning Key incorporates a broad range of features that make it indispensable. The key features flat and Phillips screwdrivers, bottle openers, a small blade, and a fitted carrying case. The locking, fold-out drum key can withstand the intense torque necessary for marching head tuning, while the long stainless steel shaft will clear hardware. The ergonomic handle is built from high-grade die-cast aluminum.
