If you have a chain with a master link: To find the master link, look for a link that looks significantly different when viewed from the side. This is where you will break the chain. The master link has a pin on one side that inserts into a notch on the other side.

A master link or quick-release link is a roller chain accessory that allows convenient connection and disconnection of a chain without the need for a chain tool. It acts as a set of the chain’s outer plates, so joining two sets of the chain’s inner plate ends.
In order to shorten the link without a chain tool, you need an alternative tool like a hammer, pliers or thin nail. They will assist you in pushing the pin easily. You can position the chain over a socket, and hit it with a hammer. Then, you can now pass the bolt all throughout the open holes.
However, even Shimano is now changing its tune and its latest 11 and 12 speed chains are available with master links.
