Final answer:
The use of "double-notched" shears is not directly referenced in the provided information, but they might affect cutting patterns in a manner analogous to changes in tool design seen in the examples given.
Step-by-step explanation:
Using "double-notched" shears in a context similar to examples provided regarding a comb experiment or three-blade design, typically relates to a modification of a tool or device for a specific purpose. The double-notched shears, not directly referenced in the excerpts, do not appear to be related to the physics concepts of static electricity or blade design efficiency.
However, if one were to infer based on analogous principles, these types of shears could potentially provide a different cutting pattern or texture due to their design. It's important to note that without a direct reference to the shear's characteristics or intended use, only a speculative connection can be made to the provided information.
