AI Technical Summary
Technical Problem
Conventional putty spatulas with a sandwich structure face issues such as difficulty in applying the blade parallel to the wall surface, reduced effective length of the blade, and finger contact with the wall or putty during application, leading to inefficient putty application and poor finish.
Method used
The putty spatula design features a blade portion fixed on the lower surface of the grip with a slight bend or inclination, allowing for near-parallel application and preventing finger contact while maximizing the usable blade width.
Benefits of technology
Enables smooth and efficient putty application with a wide effective area, reducing scrapes and improving work efficiency by maintaining blade length and avoiding finger contact with the wall.
