After some initial success with controlling the opening mechanisms of the claws, we constructed some full-scale claws to test out cracking the eggs. However, we soon realized that the smooth surface of the claws was not capable of providing the resistance necessary to crack the eggs, as they would simply slide right off.

Next, we attempted to increase friction by adding small spikes to improve the grip, but these were still insufficient to hold the egg in place. To test if further time investments in improving the grip further was worth investigating, we manually held the egg in place, and attempted to use the trident to crack the egg. The trident ended up creating a hole in the top of the egg instead, which we hypothesized was due to the lack of pressure from the bottom.

After watching some infomercials about handheld egg-crackers, we had the idea of inserting a Thus, we decided that if 3D printed plastic was insufficient, we would use an actual blade.
