Hi Freefeet, I've been looking back on this thread at your posts. Are you an angry young man or something because your posts all have the same attacking tone. your latest was an attempt to know more than Loripo, about scalpels, well Lori didn't say scalpels 'for human medical use,' as I remember. Maybe it is your terminology, but I feel it is my duty to you, to tell you that it comes across as very aggressive, over critical and often quite unpleasant... My posts are often not as they should be too, including this one, but the difference is that I KNOW how what I say will sound to the reader, but I don't think you do..Just a thought... Posie...

Been there, seen it.

Anyway I don't want to get involved in a public 'my willy is bigger than yours' debate. Our shooting experiences are not really a suitable subject for this forum. You can P.M. me if you want 'freefeet' and we can exchange experiences there if you like.

I suspect he's an insecure youngster. That's all well behind me - one of the advantages of being a 'person of advancing years'. Come to think of it, probably the _only_ advantage!

I found this which I think is a primitive tool(I say primitive but I couldn't make it) ,at a Fox earth near Broughton down,this has a few barrows on it.Is this an example of knapping?Could any natural process account for this.It is about 8cm across and the back is flat.P.S I dont think the fox done the knappingCheers Jason

Here it is from another angle. yes I've downloaded the same photo twice,sorry.

I'm no expert but:

I think the white coating is very much older than humanity and therefore you should be looking at the darker, fresher surfaces.

The 'giveaway' evidence for humans working a flint is a 'conchoidal' fracture:

Conchoidal fracture - Wikipedia, the free encyclopedia

Just the one surface showing a conchoidal fracture could be the result of a natural accident. If there is more than one, evidence for a worked flint starts to build up.

Some flints are found that look like they've been worked to a useful shape, but the fracture planes show no evidence of a conchoidal fracture. The fractures are the result of frost damage, and I understand are referred to as 'starch', apparently because of their similarity to starch grains.

Yeh I was looking at the circular depressions on this,but these as you say appear to have the original surfaces.It gave the impression of a small axe type tool just needing the attachment of a handle near that fracture.Cheers Jim
