Final Design:

This design was chosen because it had the highest score in the decision matrix. None of our preliminary designs (A-C) were acceptable. For the final design, threads were removed to save space in the shaft for storage, the blade and shaft were made lighter by decreasing the size of the parts. After redesign, the part was put through the decision matrix and greatly outperformed the other designs.
