The Obsidian Scalpel is cold to the touch, representing the void of space from which the Grays observe. Its razor-sharp edge never dulls, symbolizing eternal precision in competitive evaluation. The blade is completely black with no reflection, embodying the obsidian nature that absorbs rather than reflects light. It emits a low hum, representing the cosmic energy that powers all observations in the Wednesday Johnny League.

The Obsidian Scalpel serves as the instrument of bag tag transfer - when a player takes a tag, the Scalpel performs the cut that surgically removes competitive status, permanently altering the cosmic masterpiece the Grays have been painting across the cosmos since first observing humanity's geometric games.
