那一小片金屬本身
兩個都是同一片金屬，只是一個保持尖的、一個被壓成兩隻腳。
noun · B2
A small thin nail. Instead of a wide flat head it has only a tiny head, or a small bump sticking out on one side, so once it is hammered in it hardly shows.
細釘、無頭小釘
核心畫面
Picture one thin piece of metal, small enough to hold between two fingers, with almost no head on it. That is the whole word. Leave it pointed and drive it into wood and it disappears into the surface, holding the join without showing. it and split it into two legs and it goes through a stack of paper instead, opening out underneath to keep the sheets in place. Same little piece of metal, same job — hold two things together and stay out of the way.

可以想成一小片細細的金屬，小到用兩隻手指就捏得住，而且幾乎沒有頭。整個詞就是這個東西。讓它保持尖的，敲進木頭，它就整根沒入表面：接合處固定住了，卻幾乎看不到痕跡。把它壓扁、分成兩隻腳，它就改成穿過一疊紙，在背面張開，把紙夾住。同樣一小片金屬，做的也是同一件事——把兩樣東西固定在一起，然後自己盡量不被看見。From the word’s history
Wiktionary traces brad to Late Middle English brad, a variant of brod(d), from Old Norse broddr meaning spike or shaft. The old sense is simply a small pointed piece of metal, which is still exactly what the word names today.
依 Wiktionary 的記載，brad 來自中古英語的 brad／brod(d)，再往前是古北歐語的 broddr，意思是「尖刺、桿子」。這個舊意思就是「一小根帶尖的金屬」，跟今天的核心畫面幾乎完全重疊。後來紙用的那種雙腳釘沿用同一個名字，是把同一片金屬改了形狀，不是換了一個詞。
