The long, straight points are called “full splice” points. This style of gluing two pieces of wood together is considered one of the strongest styles of wood joints due to the amount of surface area between both pieces of wood. Thin wooden veneers are carefully cut to fit between the two main pieces before they are glued together to make this beautiful design.
The curved, arching colored pieces are called “butterfly splices” due to the pattern often resembling the wings of a butterfly. This effect is created by slicing the cue at an angle and gluing it back together with various colored veneer sheets between the pieces. After the cue is turned down and finished, these veneers result in a beautiful arching colored patterns.
