This divot tool is made from Black & White Ebony (Diospyros embyopteris) a rare member of the Ebony family native to Southeast Asia and India. The wood is known for its contrast of light and dark colored grain. While most Ebonies are in the ironwood class this member is slightly lighter. I can't find information on the specific gravity but it does float in water and going by feel I would guess it's around .85 (for comparison Red Oak has a specific gravity of .56). The grain is very tight and close pored which allows it to take an unusually smooth polish.
The tool is 2-5/8" long and 7/8" wide. The prongs are 1-3/8" long. Beautifully finished with Teak Oil followed by a 3-stage polish with Carnuba Wax as the final step.
This tool has been designed to be used with a pushing motion as opposed to a lifting motion. Research
performed at Kansas State University has shown that repairing pitch marks using a pushing motion is much kinder to the sod's root system, enabling greens to heal faster and is recommended by the Golf Course Superintendents Association.
