I just got my racquet back from a friend who strung it for me and i was putting head tape back on... I am slightly anal about how perfect it is put on so i was using a razor blade to trim it(horrible horrible idea ) and i put a nick in the string accidentally... so pretty much i hit the ball once and it snapped. . I dont recommend ever using razor blades around your racquet, unless you want to waste $15 or more. Just wondering has anybody else had experiences with ruining strings such as this?
