I had Craftsman flare nut wrenches almost 20 years ago Maybe more like 15.... I would never touch one again. Incredibly terrible in my personal opinion. Of all the tools I ever upgraded from Craftsman to Snap On, flare nut wrenches were probably the biggest improvement.
Disclosure: I had the Craftsman when I was a teenager and possibly into my early 20s, when I couldn't afford a super new car w/o rust. But when I upgraded to Snap Ons, at that time I was still driving the same sort of vehicle, but the improvement in being able to get lines off was VERY significant.
Edit: I honestly think using Craftsman tools is one of the worst decisions a person can make when trying to work on their car, and I truly mean that. So many issues for me have been solved by just getting Craftsman out of my toolbox. I know not everyone will agree, but as far as my own experience goes, this is not an exaggeration at all. One could argue my experience increasing over the years helped more than upgrading the tools (and there is certainly no replacement for experience), but in many cases I used my old Craftsman stuff side-by-side with the various brands that replaced it, and felt instant differences in many cases.
