Cutting tools of some kind?

[Sam James]

Hi All, I have just joined this forum and I am very glad to have found it as I have a good collection of neolithic tools over here in the UK and there is no easy way to identify the ones I am not sure about. I have had some great responses and I am very grateful, I am posting up some more, so here are some pieces I am finding which all seem to have a cerated edge and a flat top end. I have seen tools a bit like this, are these cutting tools of some kind or nothing?
Cheers
Sam
