Do you have a Vibra-Knife? We have blades! For over 20 years the Vibra-Knife was one of the most successful auto glass cut out knives in the world. Today, thousands of these tools are still in use. Equalizer Industries purchased the rights to make the blades and the tool when the original manufacturer ceased production. Vibra-Knife blades are now available. We have updated the design to make the blades thinner. Our tests show the blades cut easier than the original blades since the thinner blade causes less resistance. They are made of the same material and use the same hardening process as our Z blades. Made in USA.
