Cutting the string. The reason for the flush cutter is to trim the string up neatly. Toe nail clippers will work but won't last as long. You can always get your bent nose pliers and side cutter locally or on line but get some good ones.
EDIT: something else you may want are some shears for cutting the string out of a racket.
