Cloth Tape
From BelegarthWiki
Cloth tape, also known as hockey tape,grip tape or athletic tape is a thin, light, tacky, clothy tape that is widely used in weapon construction, both as an adhesive (such as when constructing an arrow) and to cover non-striking surfaces of a weapon, such as incidental padding, pommels, and hafts. Most cloth tape is black, though it is also available in a variety of other colors.
Andover brand hockey tape is superior to Renfrew (the brand available at Dick's Sporting Goods').
