Tools for folding pieces of sheet metal and methods of manufacture and use thereof

A method comprising:

• causing a user to access a tool including a first pair of jaws, a second pair of jaws, and a body, wherein the first pair of jaws is spaced apart from each other at a first distance such that an edge portion of a piece of sheet metal is receivable therebetween and the first pair of jaws is configured to form a hem on the piece of sheet metal via the edge portion being bent when the first pair of jaws is moved relative to the piece of sheet metal or vice versa, wherein the second pair of jaws is spaced apart from each other at a second distance greater than the first distance such that the hem is receivable therebetween and the second pair of jaws is configured to bend the piece of sheet metal containing the hem when the second pair of jaws is moved relative to the piece of sheet metal or vice versa, wherein the body spans between the first pair of jaws and the second pair of jaws;
• causing the user insert the edge portion into the first pair of jaws to form the hem on the piece of sheet metal via the edge portion being bent as the first pair of jaws is moved relative to the piece of sheet metal or vice versa;
• and
• causing the user to insert the hem into the second pair of jaws to bend the piece of sheet metal containing the hem as the second pair of jaws is moved relative to the piece of sheet metal or vice versa.

A method comprising:
