Fibre tape

Also known as strapping tape, fibre tape is a semi-transparent adhesive tape, reinforced by strands of fibreglass. Used by some fighters to prolong weapon life, it is very hard to tear sideways, but can be easily split lengthwise. While it is very strong, it is not very adhesive, and sticks best to itself.

Helpful hint: If lacking a cutting implement, strapping tape may be broken by folding the non-sticky side back on itself, rubbing in a crease with your thumbnail, and then giving the tape a good sharp tug.
