I have a set of ten RP Craftsman wrenches (1/4 to 1 inch), made in Japan and marked BF, that were bought new circa 1982-84. One of two sets I got at the time -- the other is probably still in use in my old lab.
For a long time I was disappointed in them not to see Made in USA. Times change, don't they? They still aren't my go-to set, but I gotta admit they're beautifully made.
