How do you split a chain without chain tool?

To split a chain without a chain tool, you can use a flathead screwdriver or a similar tool to push the pin out of the chain link. Place the screwdriver against the pin and tap it gently with a hammer or another hard object until the pin is partially or fully removed. Be cautious not to damage the chain or the surrounding links. Alternatively, you can use pliers to grip the chain and twist it until the link opens, but this method can be more challenging and may not be as precise.
