Paint jobs have become more complicated. Anywhere from three to as many as seven layers of paint are being applied. If you damage the paint you are in trouble! To help you stay out of trouble, Equalizer® has added a soft, Neoprene cover to our GK380 Standard Cold Knife to help prevent paint damage and give the cold knife a comfortable, soft, non-slip grip. The covered wire on the pull handle prevents damage to the hood, vertical posts and other painted parts. Now you can know the size of your blade at a glance: yellow is 3/4", red is 1" and green is 1-1/2". Always put the same size blade in the same color tool and you will know what length the blade is.
