The Luka is a yo-yo produced by Ioiô Fênix. It is a plastic yo-yo with a fixed wooden axle, similar to the classic Russell models, but it has a slimline shape rather than the bulge-faced profile. It is a best-seller for Ioiô Fênix, and comes in different colors with different side cap designs to help it appeal to younger players. Its profile is ideal for looping play and performing the basic tricks.
