Calfskin is particularly valuable because of its softness and fine grain, as well as durability. It is commonly used for high-quality clothing, shoes, wallets, and similar products, as well as traditional leather bookbindings. In these contexts, just "calf" is commonly used. Fine calfskin is one of the skins used for vellum and parchment manuscripts.
