{"product_id":"formal-variation-in-australian-spear-b-j-cundy-9780860546931","title":"Formal Variation in Australian Spear and Spearthrower Technology","description":"Described as an attempt to increase understanding of one of Man's simplest and possibly oldest technologies, this book brings an engineering perspective to formal variability in these weapons.
