Safety Utility Knife / Tool

Safety Utility Knife
Safety Utility Knife

The blade becomes blunt after being used for a long time, so we need to break the blade usually because we always expect more convenient cutting, but breaking the blade is dangerous, the blade will fly out to hurt people inadvertently.
We redesigned the knife tail plug, making the structure capable of bending. Pull the plug out and set to the front of the knife, then we can be assured of the broken blade, the blade will be broken into the plug, and can't fly out to injure people, so it is safe.
