Technically, the entrepreneur who went by " Uncle Levi" didn't invent the copper rivets on denim " waist overalls" that became his firm's stock-in-trade.

从技术上讲，这位被称为“李维大叔”的企业家并没有发明牛仔“腰部工作服”上的铜铆钉，而这种铆钉正是利瓦伊公司的存货。

This was really a combination of things then – the denim, the copper rivets – that produced what we now call blue jeans.

这实际上是当时各种东西的组合——牛仔布、铜铆钉——造就了我们现在所说的蓝色牛仔裤。
