The stainless steel Klein Folding Insulation Cutter features a dual-edge design�one smooth edge for general-purpose cutting and one serrated edge for tougher, more fibrous insulation materials. This dual functionality provides flexibility and efficiency, allowing you to tackle different types of insulation with a single tool. The compact folding mechanism allows the cutter to be safely stored and easily carried in your tool belt or pocket. It folds down to a slim profile, protecting the blade and making it convenient to transport between job sites.
