Sandstone abrading piece?

[autographcollector11]

I took better pics of a piece I showed before. I noticed some lines in each end and confirmed it was sandstone. The area was never plowed so it not plow marks. Could these be abrading marks. I hope the lighting is ok. It looks so symmetrical as well on the end. What do you think?
Again thanks for your help

Natural I think maybe lightly ticked by a plow. Here is one that my lovely friend is holding for me to take a pic.Sometimes they are just a single line as well. Used to sharpen awls and some some shafts/arrows. Multi purpose tool.

Actually the area was never plowed-all primitive land....

Here is one that i have inside and it has seen heavy use, the second photo of your'se looks like it has seen some use as an abrader. This one is a soft abrader stone there is some that are made of harder stone.

Here are a few better pics that really show the lines and grooves....does this help at all?

Looks like random implement strikes to me even though you said it's never been plowed.

Random strikes or scrapes. If it had been used enough to create all of those marks, they would be more orderly and probably on flat surfaces vs curved surfaces.

Just a fine rock.
