The beverage shaker has a tumbler, a top or cap, and a shaving tool incorporated within one of the tumbler or top of the beverage shaker. The shaving tool typically has circumferential ridges, spiral threads, or other protrusions and a pointed end to bruise any fruit added to the beverage being mixed and to create shavings from included flavor ingredients and ice. The shaving tool may be removably disposed in either the tumbler or the top. The shaving tool may have a liquid-filled hollow portion. More than one shaving tool may be commonly connected to the tumbler or top.
