All guitar players have been painfully poked more than once by the sharp ends of the strings where they wrap around the tuners. In the 1930s, Kluson marketed “SafeTiString” tuner posts where the string ends could be neatly tucked away in a slot in the posts to “banish the peril of injured, cut or bruised fingers.”
Neat invention, but apparently too late to save the poor woman pictured in this advertisement reprinted in Vintage Guitar magazine in the Feb. 2013 issue. She appears to be bleeding to death.
