... Twrch Trwyth is pictured as a formidable boar at the head of his offspring, consisting of seven swine, and the Twrch himself is represented as carrying between his ears a comb, a razor, and a pair of shears.  The plot of the Kulhwch renders it necessary that these precious articles should be procured; so Kulhwch prevails on his cousin Arthur to undertake the hunt. (Celtic Folklore: Welsh & Manx, v.2, 1901)
