I'm not sure about machinists, but my father is an 'old-school' drafting table/slide rule (both of which he has since relinquished) mechanical engineer, and he commands a premium due to his 'hands-on' nature with problems.

He can sketch a picture and create a tool from the sketch in essentially the same day, whereas his counterparts take just as long just to sketch the tool in a CAD program of some sort.

He has always had a problem with CAD design. He can navigate it, but he has difficulty with actual modeling. Luckily he is at such a rank in his profession to where he has an intern assigned to him to translate his graph paper sketches into document-able CAD files and do other computerized clerical work that he's not up on.
