The Calvin and Hobbes Wiki
Pete the barber

Pete is one of several barbers that Calvin has gone to. Although Calvin may not be entirely satisfied with his haircuts, he praises Pete's work out of (unfounded) fear that he may cut him up with his razor.

Pete is a rather unremarkable-looking man with blond, flat-top hair and a prominent nose. He wears black pants and a loose white vest.

It also seems this is Calvin's usual barber as Calvin's Mom says "Give him the usual, Pete".
