Hive account@gavvet - It is amazing to be able to actually spot this sort of stone age tool manufacturing spot. I think I have been blind to all such clues in the past when I wandered on the mountains! I wish I had your blog then. I am going to keep my eyes open now for irregularly shaped chips like that and also for trapizoidal shapes. Also - I am blown over to see what an ingenious way our ancestors carried the cone shaped rock and struck so many blades from it!

Thank you for this informative blog. Upvoted.

Update at my end is that I am doing a 'Photospeak' series with my memories from Africa - with just a photo with minimal words - Letting the picture speak for itself mostly. I would be honored if you can take a look at latest one when you have time and provide your valuable comments. Thanks
