So I have never heard of this before, and I saw this on a golf site, its called a groove sharpener. What is the point of this? Anyone do this regularly?

nothing a 1 dollar metal saw would'nt do I think. used one to deepen an almost totally disapered bottom grouve on a wockey sand wedge and it worked fine.
yet if you use a groove sharpener be carefull of the result on width of grooves which are limited by rules.
