After several years of battle with an '84 Magna I am now the undisputed Master of the Inventive Curse. Yeah, I know, there are Shovelhead owners who might contest that title, but I'm confident in my ability to turn the air blue within nanoseconds. After all, nothing on the Magna can be substituted with duct tape or baling wire.
A good "classic" bike mechanic also knows that the quality of the tool is directly proportional to the distance it bounces as well as the timbre of the ringing. For example my old set of No Name metric box end wrenches I bought at the Pep Boys on Sunset in Hollywood in 1974 do not ring as clearly nor fly as far on rebound as the Snap-on box ends I stole from my father-in-law.
