The Gladiator by Dif-e-Yo is a custom, made-to-order yo-yo and an all-aluminum version of the Spike-Fly. It features a KonKave bearing and uses Dif Pad response. Unlike the Spike-Fly, however, its side spikes are machined as part of the yo-yo's body design. Two versions were released, one with solid spikes and one with bearings in the spikes. The Gladiator was also entered at the yo-yo mod contest in the 2004 Worlds.
