When Adi Dassler started his small business in 1920 and began to makes shoes, he used scraps of material left over from World War One. Using leftovers like army utensils for tools and using strips of leather from army helmets for shoe soles he would go to his mothers former laundering shed and make his shoes. Because there was no electricity in the shed, he made a machine that was a leather trimmer attached to a bicycle frame so he could peddle to cut the leather. I think it is interesting that he went through all that trouble of scavenging for all those scraps just so he could make a couple pairs of shoes.
