Lets take a look at experience first. Does a person have thirty years experience or one year experience thirty times? In fact if one had the same job for thirty years this person experience will depend on the job or vocation they are in. A craftsman experience would depend on employment location and craft. A machinist gains experience slower than a tool and die maker. For example a machinist works from a engineering drawing. Experience is gained by new shapes and materials. In contrast a tool and die maker is given a drawing of a shape and from this drawing must take in consideration material characteristics to create a die that makes the part.
The difference is education of a machinist and tool and die maker.
