Found this while doing some work around the land. Kinda strange...I'd love some input. Approximately an inch long and about 3/8" wide. Could this be a needle sharpener? Santa Cruz CA.
With all due respect rock, what would create a shallow groove in a small stone like this? It's not broken and it doesn't look like something caused by a machine. Im trying my best and for all intents and purposes you all are my mentors. When I look at this and hold it I cannot logically think of any other way it may have been formed other than a human repeatedly sharpening a needle or fishhook on it.
I don't know. I'm not trying to be contentious. I greatly respect the more senior members and their knowledge and sharing. I ask questions to learn and have to logically work through things. Thanks.
