Originally called the Enardoe set, these are available again after all these years! The traditional set of color-changing knives used in the 30s, 40s and 50s. Some called the “African Blow Knives” because they only open or close when the performer blows on them. Simple, strong ad effective. A knife changes color several times, disappears and reappears in the performer’s pocket. Two knives: white/white, black/white. With complete illustrated routine.
