飞去来器,顾名思义,就是飞出去还会再飞回来的器具,所以又叫回旋镖、飞去飞来器。它的形状有“V”字型、三叶型、“十”字型、多叶型等多种。飞去来器本来是用坚硬的曲木制成的一种武器,用于狩猎和战争。熟练的投手掷出的飞去来器能在空中划出不同的飞行曲线,在飞行过程中击中目标。投掷者还能让它完成飞行目的后飞回自己手中。 Fly to the device, as the name suggests, is flying out of the appliance will fly back, so called Boomerang, fly to fly. Its shape has “V” type, trefoil type, “ten” type, multi-leaf type and so on. The fly-off was originally a weapon made of hard-wood for hunting and warfare. A skilled pitcher hurls a different flight curve in the air and hits the target during the flight. The thrower can also make it fly back to their own hands after completing the purpose of the flight.
