Yep, there are even machines to do it quickly. Still nice to know how to sharpen a chain to a certain degree so you don't have to change the chain multiple times before lunch. Changing the chain easily takes a few minutes (opening the side, loosen the chain, change chains, tightening the new one to correct tension, closing the side.)
