wilson river ice giant

This is my first post, new to the hobby. Just started finding rocks while fishing. Found this sucker in a river gravel bed, just the tip was sticking up.

Not really sure what it is but the blue area can't be scratched with steel and seems to kinda flake like an arrowhead or something.

blue jasper?

Looks like chert or maybe shale to me.
