The Klein Tools folding insulation cutter has serrated stainless steel blade cuts through foam and fiberglass with ease, and folds back into the comfort-grip handle for added protection. The lockback mechanism secures the blade open for heavy duty use and stable cutting. After the job is done, you can easily fold the blade back down, even with work gloves on.
