Made of durable carbon steel, the CenterFire Insulation Knife Blade with a non-serrated edge quickly cuts through foam and fiber insulation products while eliminating dust and debris. It easily cuts notches and squares around outlets, and it has just the right amount of flex to efficiently cut expanded foam around windows or circles in sheets. Choose between a 3", 4” or 7” blade, all fitting standard utility knife handles and a Sawzall-type reciprocating saw. Order a single blade or stock up with a 3-pack.
