顶针在英语里怎么说

In English, a "顶针" (dǐng zhēn) is a type of sewing needle that is used to reinforce or strengthen a seam. It is also known as a "topstitch needle" or a "topstitch wheel." To use a 顶针, you would thread it with matching thread and use it to sew over the top of a seam, creating a decorative and functional stitch that helps to hold the fabric in place and provide additional strength to the seam.
