Under my thumb

Dopo aver visto questa foto ho controllato e l’impressione iniziale è stata confermata: tutte le cerniere che ho trovato sottomano erano marcate YKK. Cos’è?
YKK was founded in Japan as a zipper manufacturing company in 1934 by Tadao (pronounced in English as Tah-dah-o) Yoshida. In the early years, Mr. Yoshida’s company carried his name; it was called Yoshida Kogyo Kabushikikaisha—or “YKK” for short. (That long Japanese name translates roughly into English as “Yoshida Company Limited.”) Over the years, the letters “YKK” were stamped onto the zippers’ pull tabs.
