Whale harpoon
Possibly the pointy end of an old push plough

i am sure its one of those ploughshare things actually. looks almost exactly the same as in you photo wally. good work everyone. give yourselves a pat on the back. even you silver. very helpful to help us eliminate certain things. hahah
now i just have to work out what to do with it. great.... more reading.
heres the photos of the attachment end as promised yesterday. thank you for helping everyone.

It does not look like any of the things mentioned here to me, and looks natural. Firstly, the original big lump looks like conglomerate (perhaps iron-cemented gravel) and warrants breaking up and panning off. After "cleaning, what remains looks like a big bedrock boondie that was in the conglomerate or that it rested on in the stream bed. Are you sure that it still reads, or was it the conglomerate that you broke off that reads? The shape resembles a very tight fold in sandstone, with slate in its core showing an axial planar cleavage.

axial planar cleavage is planar and occurs parallel to the axial surface of the fold (parallel to a plane that folds the two fold limbs in two). Where slate and sandstone is folded together (imagine folding a magazine and its thick cover so that it is a tight V shape), the cleavage is often only visible in the slate (the pages), not the sandstone (the thicker cover). It is usually easy to split the rock along the parallel planes of cleavage in the slate part.
of the core of the fold.
