Saw chain

Saw chain is a replacement part for chainsaws, meant for cutting wood when the chain and bar need to keep the tool working properly. By our assessment, its value is in that very specific job: a sharp, correctly fitted chain makes a saw cut cleanly and keeps the machine useful. The trade-off is maintenance, because chains need sharpening, tensioning, and the right fit for the saw they belong on. In practice this is not a glamorous product at all; it is bought, fitted, adjusted, and then judged by how well it bites into timber. It sits well inside the chainsaw ecosystem and nowhere else, so anyone outside that use case will not get much from it. The name is plain because the thing is plain, and the ceiling is simply the machine it supports.
