In English-speaking lore, saying a lucky thing out loud and then knocking wood is an undo for hubris — a tap that “takes it back.” Origins split among sacred trees, church timber, and children’s play. Korea has other sentences — a spit, thrown salt — and the salt landing stays on mineral rites. This page is the Western knock. It sits in a family with broken-mirror and Friday-the-13th talk, with a different prop. A desk tap does not decide an interview or a surgery.
The classic order is a boast, then contact with wood. Knocking a plastic laminate is a later compromise. No official species.
Spit, salt, and house rites are other materials. Do not translate them into one knock. salt-for-luck covers salt.
Do not hammer thin veneer or glass ornaments. Old timber with nails is trauma. A desk tap does not replace a signature.
The crossed-fingers landing is a hand-shape omen. This page is the sound of a tap.
