Flint Tools?

I have discovered in our Norfolk garden what appears (to me) to be flint tools:

2 flint toolsThese I unearthed whilst gardening in our vegetable plot. I took a series of photographs to send to my daughter who is a physics teacher and may have contacts who could help verify (or otherwise) whether they are, or not, flint tools.

The photos I took include a set of images around each tool such as this:

If anyone can advise on this I would appreciate it…
