I've been on a research tear, and in the process of reading very early (c. 1950, 1951) issues of
PS: The Preventive Maintenance Monthly magazine, I ran across a series of these recurring "Hand Tool Clinic" features.
You can see the others in the Pliers and Hacksaws threads.
If you're not familiar with
PS, the US Army recruited a young cartoonist named Will Eisner (
The Spirit, Blackhawk, others) into the Ordnance Dept during WWII, and from Aberdeen Proving Grounds, where all vehicular maintenance and training was HQ'd, he led a team as a warrant officer in making preventive maintenance more enjoyable (and more effective!) to mechanics by publishing mimeographed flyers in cartoon form, featuring his loveable loser character, Joe Dope. During WWII, they were published in
Army Motors, but in 1950, Joe, Connie Rodd (pinup model in uniform), and Half-Mast McCannick (letter columnist), they became their own publication as a "postscript" (hence the name). Eisner would go on to become one of the most famous and influential cartoonists in history, including credit for the very first "graphic novel" in 1978. The Eisner Award is the highest annual honor in comics, and it's given at the Eisner Comic Books Hall of Fame.
