Cartridge cutter is a necessary tool for caulk guns. Compared to utility knife, it’s a safe and ergonomics accessory. It’s covered by an impact-resistant ABS body so that you won’t directly touch the blade. Besides, it’s equipped with a quick and safe switch on and off button. Once you press safe switch button, the blade will pop up. You won’t easily be hurt by the blade. The ergonomics design makes you effortlessly cut the threaded nipples of cartridge and nozzles. It can also cut a perfect angle on all cartridge nozzles. If you prefer to design your own cartridge cutter, we can paste your own dome sticker on the cartridge cutter. It can reveal your own brand product.
