Claw spanner / hand tool

Claw spanner

The invention of Claw Spanner aims to design a utilitarian tool to optimize people’s working efficiency. The problems inherent in adjustable spanner have been the basis of my design logic. By analyzing the deficiencies of these tools I was able to find solutions to the damage caused to nuts by the high slippage of normal adjustable spanners. My design outcome “Claw” spanner address the issues by controlling the slider's position to fit nuts of varied sizes, the desire that one spanner fixes all sizes of nuts has been achieved. Currently, I have patent my work regionally. Hopefully in the near future, I can witness the mass-production of it.
