This is the Fireball in a butterfly shape. It is a little lighter than the Fireball, but the difference in weight does not seem to affect performance. The Saberwing Fireball is a Teflon transaxle plastic yo-yo. The Teflon transaxle gives this yo-yo very long sleepers. It has a fixed gap width that is set at a good place for most yo-yo players. It is not a great looper, but is decent at both looping and string play.
