The present invention allows a user to select a handle that is ergonomically friendly to a user's hand and replace it with the replaceable handle that is design to fit over a soldering iron rod. There are a number of advantages to the present invention. One of the advantages is that a user can choose its own handle with the desired, shape, size, color, and material. Another advantage is that since each user has its own handle, hygiene problems may be minimized. Still another advantage is the cost savings because as the replaceable handle wares out, only the handle needs to be replaced rather than the whole soldering iron.
