Hello, I'm wondering if anyone can help identify what this stone is. It has a somewhat pointed shape and smooth finish. My fingers sit comfortably on the grooves/indentations on the side of the stone, and there's an indentation on the bottom that fits my palm. This could be a coincidence but figured I would see if anyone has seen something like this. I purchased this in a rock and mineral collection which included an old tool that I was able to identify, which leads me to believe this may be one too. Any help is greatly appreciated!
