First released in 2005, the Underdog 1 was a modified version of a Freehand 1. It was an aluminum bodied yo-yo with one side deeply recessed. You could fit 5 stacked friction stickers in the recess, allowing you to customize the amount of response you wanted. It was also one of the first yo-yos to have an inner lip on the rim for thumb grinds. It had a Teflon hard coat finish.
