CNC-machined in Taiwan from stiff 7075 T6 aluminum with a unique design featuring concentric grooves for weight reduction, while creating a visual cue reminiscent of vinyl records. Maybe if you figure out a way to put it on a turntable and spin it backward, you'll hear a secret message from the devil!
