It can scratch a kitchen knife (probably mohs 6-7 🖐️🤚) I'm sorry. I had to. Found at a saltwater beach in Halifax Nova Scotia. Seems to be made up of two types of rock. Thanks geologists! Might be some kind of metasiltstone based on a geological map i own.
I love natural stones! I went to a random beach and found a flat, rectangular stone. I flattened it even more on some cinder blocks and it sharpens! it doesnt cut that fast, but it makes some wicked sharp edges! (at least for me🫤) I got 3 shaving edges in one day!!!!!!!!! the stone makes a dark grey slurry.

2nd Edit: Found in Nova Scotia in eastern Canada.
