  • Blade made from durable 3CR13 stainless steel for heavy duty use

 “Cutting through heavy-duty materials is often a requirement on the jobsite, and professionals need a tool that allows them to do that quickly and safely,” says Ryan Gilmore, associate product manager at Klein Tools. “Klein’s new Folding Insulation Cutter allows professionals to accomplish both of those goals. The folded blade keeps the user safe by keeping the cutter from piercing through tool pouches and bags.
