Thanks Frank!!!
Ditto. I've printed it and put it into a plastic sleeve for shop use. But what's this "Robertson" thing? I thought it was "McFeely"?

Robertson was a Canadian who invented the square drive. Designed not to cam-out when overtightened (as opposed to the Phillips drive, which is designed *to cam out* when overtightened).

Got calls into Webster right now. Tellin' 'em to put McFeely in their next edition or a pack of 'dorking lawyers will be on 'em faster than a goose on a june bug...
