Many of the poorer villagers – both Jenische and non-Jenische – then went about peddling handicrafts made of wire, among these, mousetraps. The upshot was that many families’ livelihoods improved markedly. These wire handicrafts were made mostly by women at home, while the men became travelling mousetrap salesmen, going well beyond Germany's current borders to sell their wares, into what is now Poland and the Czech Republic. The pedlars used a secret language amongst themselves, Jenisch. Growing industrialization began to hinder the trade noticeably by the early 20th century, until in 1970, it was brought to an end.
