Picked up these this year, just laid on the fields - top left is jet though.
Flint doesn't occur locally here so any you find was carried almost certainly by man.
They could just be waste from making a more impressive tool, but they have sharp edges and can still function like a penknife.
Two especially do sit very nicely under your index finger for cutting or scraping.

I saw a Time Team episode where Phil Harding did some flint napping. It was quite amazing how sharp the flint blades were.
I wouldn't have a clue if those were tools or off cuts but an interesting find. ____________________ Triumph Trophy Launch Edition |

Looks awfy like the stuff that I used to top up my driveway chips.
Chert.
I found several lumps when I was working in N. Africa but that was Petrified Wood.
Where the chert/flint seeps into buried vegetable remains and is then hardened into rock.
It's a very fine grain so micro details are retained.
But the wood part of petrified wood no longer exists in petrified wood. ____________________ Disclaimer: The comments above may be predicted text and not necessarily the opinion of MCN. |

That looks like chert to me. It's still workable for tools though and being microcrystalline silica will take a demon edge. Flint is a specific type of chert associated with cretaceous chalk deposits.
ETA
Not necessarily brought there by man by the way. Glaciers transport rocks huge distances. |

Used to do a bit of knapping when I was a teenager. It's a lot of fun, but very frustrating when something you've been working on for 30 minutes snaps in half.
This is about the best I did. Middle one is obsidian, but I cant remember what the other were. There's no knappable stone in my area so I ran out pretty quick.
