The apparatus is for mounting a coconut firmly for making an initiating saw cut in the middle circumference of its shell in a direction transverse to the grain of the shell such that the coconut can be split into two desired half sections easily and simply by inserting a wedge into the saw cut and splitting it with a twisting motion over an intended coconut water receptacle. It has a three-point mount for securing the coconut and a pivotable V shape saw guide for positioning a sawing instrument in making the initiating cut. The apparatus can also be used for mounting a split half section of the coconut securely for grating its flesh with a grater.
