Strings (tennis)
The material used in tennis string can significantly affect a player's performance, and even health. Several materials are used to make tennis strings. They vary in terms of elasticity, durability, rebound efficiency, tension holding capability, and manufacturing cost, among other considerations.
Strings (tennis)
Racquets are strung either with two separate strings (and thus four knots), or with a single string (resulting in only two knots). Sometimes, a hybrid of two different string types may be used in the same racquet. Traditionally, a double half hitch has been used to tie off tennis string, along with a starting knot. Recently, new kinds of knots have been used called the "pro-knot" and "Parnell knot". Along with the use of a starting clamp, this can make all the knots identical, and improve the aesthetics of a string job.
