We all have removed a windscreen with a long knife and come into a situation where the adhesive was too thick to cut through with a standard utility blade. Our solution is the 3.75" (95mm) long heavy duty utility razor blades 10 pack. These blades are strong at .024" (0.6mm) thick for maximum durability. Cut through ALL the adhesive at once with this long blade. Glass Technology utility blades will fit most utility knives as well as auto glass long knives.
