Blunt Umbrellas
The most obvious change implemented in the Blunt Umbrella is the new shape of the canopy that eliminates the sharp spikes at the outer edges. These sharp tips are replaced with "Blunt Tips" that, as well as being safer, also spread the force at the edge of the canopy to eliminate one of the most common failure points of traditional umbrellas, which involves the tearing of the canopy from the rib point.
According to the company, spreading the force along the outer edge of the canopy where the surface area is highest also creates superior tension while providing an aerodynamic and rigid profile which maximizes the performance of the umbrella in windy conditions. Further enhancing the stability of the Blunt design are secondary struts that support the fiberglass telescopic ribs to assist in anchoring the canopy to the frame.
