I found this flint this morning at Seaford Head in East Sussex. I noticed it because it is a similar size and shape to several flint axe-heads and other flint hand-tools I've seen in local museums. The area is the site of a late-Bronze Age to early-Iron Age hill fort.
To my non-expert eye, I'm sure it's probably just a piece of flint that happened to break off in that shape. I've spent most of the afternoon looking online for clues of how to tell whether it's some kind of tool or not, but I'm not really any the wiser, so if anyone can confirm I'd be grateful.

I don't think it's an axe head as it's a little small, and it lacks the tell-tale signs of worked tools like the bulb of percussion, radial lines and worked edge. Though it could well be waste from a flint working site (sometimes known as a flint factory). Maybe it would be beneficial to take it to one of those museums you mentioned for someone to take a look at it.
The photo only shows one side of it so it's really hard to say anything for sure. But I agree with Rhys that from what we can see it shows none of the characteristics of a flint tool that Rhys lists. Please post some more pics or email email@example.com if you'd like to bring it into the NHM.
