The Malleus was B.I.O. Industries' debut release. It is a two-tone colored aluminum yo-yo with a slim shape ideal for more complex maneuvers. The yo-yo's one and only production run was limited to just 100 pieces, and each unit came with a serial number. The low-friction finish on the Malleus is so slick that it is like talcum powder. It also has ridges that allow for thumb grinds. For response, there is a single recessed pad on the gray half, making the yo-yo great for suicide tricks.
