A combination blade of aluminum hinges and shatter resistant transparent plastic web used to replace metal blades of accordion storm shutters used to protect glass windows and doors in homes, office buildings, and other walled structures from the destructive force of storm systems, such as hurricanes. The present combination blade assembly includes a flat sheet of shatter-resistant and transparent plastic material forming a web between a male and female aluminum hinge. The hinges and web are held together with urethane adhesive that also forms and hardens into a mechanical spline for additional joint strength due to the hinge shape. The hinges are shaped to be interchangeable with metal blades used to make accordion storm shutters. The metal blades can be replaced with combination blades using the same methods and hardware.
