Evaluation

Final Testing:
    
Britt and I tested the final Eagle Claw at Castle Rock, a popular bouldering location. The Eagle Claw performed well, but it did not seem well-suited for these rocks, which had few food holds and required Britt to sometimes press his foot against the smooth rock walls for a quick boost, called "smearing." The sharp rubberized toes of the Eagle Claw gripped rock ledges masterfully when these ledges were available, but were incapable of providing a large, high-friction surface for smearing.

Improvements for second-generation Eagle Claws:
     
Although this marked the end of this 10-week project, I began considering ways to improve the Eagle Claw. Some of these ideas were relatively minor changes, and others involved radically different designs for prosthetic rock climbing legs used for different styles of rock climbing. I hope to continue this project in the future to perfect the Eagle Claw.
