They followed a change in shirts. Sleeve buttons appear once men's shirts have cuffs that need fastening. Earlier shirt sleeves were closed with ribbon ties or simple strings; when the stiffened, turned-back cuff arrived in the seventeenth century, a fastening was needed that could be undone and that looked like jewellery on both sides of the wrist. The object exists because a garment changed.

Why two faces and a link. A cuff fastened with a link shows one face on the outside of the wrist and one on the inside, and it holds two edges together rather than overlapping them — the barrel cuff. That is a different fastening geometry from a button and buttonhole, and it is why cufflinks did not simply become buttons.

The name arrived later. "Cufflink" is a nineteenth-century word; the earlier term is sleeve buttons, and eighteenth-century inventories and advertisements use it. If you are searching older sources, that is the term to look for.

Industrial production changed them. Through the nineteenth century, machine stamping and the growth of costume jewellery made decorated sleeve buttons cheap and widespread, and later the swivel-bar fitting replaced the chain for convenience. The chain-linked form in this blueprint is the older one and is still regarded as the more formal.

Why this is a good first project. Two identical halves means every operation is performed twice, so a mistake on the first is a rehearsal rather than a disaster. The pieces are small enough to heat quickly and forgiving of imperfect soldering, and the result is a wearable object rather than a practice scrap — which matters more for staying with a craft than most people admit.
