GT Tools makes three synthetic cutting lines, and the company is very clear about the differences between them. The Titan Cord product page says it plainly: "This is not the cord you use to save glass. Use our ZipLine for that." That single sentence settles most of the choice. ZipLine is for cut-outs where the glass is coming out intact and the hardware around it is expensive. Gorilla Cord is for old, hard aftermarket urethane. Titan Cord is for glass you have already written off, where the only goal is getting it out. This guide covers what separates the three, what they cost per spool and per five-pack, and why a synthetic line is better than wire on an aluminum body.

Powered cut-out tools handle most of a windshield removal, and every shop still keeps hand tools within reach. Manual knives go where a reciprocating blade cannot: tight corners, encapsulated glass, vehicles where the pinchweld leaves no clearance, and the jobs where a technician wants to feel the resistance rather than hear it. GT Tools stocks four kinds of manual cutter, and they are not interchangeable. Cold knives push. Long knives reach. Pull knives draw a cable through the bead. The Quarter Cutter is driven by hand or struck. This guide covers what each one does, what GT stocks in each family, and the order most shops buy them in.
