60 lbs, but Not as precise as if you were using a brake. One of the factors we strive for in stringing is consistency. Though the pen cap, socket extension, and S-hook method, are probably more consistent than using your hip and arm to hold the racket. You are also putting undo stress on the handle of the racket.
