Bond of Flame

The Bond of Flame is a keyblade given to Sora by Axel after he sacrifices himself to save Sora from the Nobodies in Betwixt and Between in Kingdom Hearts II. This keychain resembles Axel's chakrams, and enhances fire-elemental attacks. It can also be noted that the shaft, which resembles an hourglass-design, can also be seen as an 8, represeting Axel position in the organization.
