@bruces "I've been cutting my hair with stone tools..." Video is in fact of a young woman cutting his hair with stone tools.

(I did wonder if there was going to be a Basque connection here. Their words for many cutting tools, e.g. knife, axe, begin with "stone" [aitz]. Guraizeak [scissors] looks like it might have a variant of that syllable in it but I'm not a Basque etymologist.)
