-One decision that had to be made with this component was the size of the two circular holes at the bottom which lock the blade in place via screws.  The number of prongs at the top (27), their shape, and the cut out angle that cuts into them were all decisions as well.  Finally the thickness, length, and width were all decided upon.

-User tests in which only the stationary blade is variable can measure performance.  By varying the design of the stationary blade only, its performance can be compared to other stationary blades, and its relative performance would thus be evaluated.  Since stress on this component would most likely be minor, stress tests would not be necessary.

 The most important thing for the blades to do is to cut hair. To evaluate their performance, one could measure how much hair is cut per pass as a percentage.
