Cracking an egg, like tying shoe laces or brushing teeth, etc. is an ANPPN (activities of no particular prosthetic need). I can put a knot in a tie, or load boxes into a car, or mount a ceiling man, wearing no prosthesis (no problem), a body powered hook (better balance of loads), or a myoelectric "bionic" hand (cumbersome, not reliable). There are activities where a prosthesis ADDS to the abilities I have as unilateral below elbow amputee; cracking eggs is not one of these. In other words, to show that I can wear a prosthesis to crack eggs is just as informative as saying that I can drink a beer or watch a movie with it. Ultimately, I do any of these without the hassle, discomfort and insane expense. Check here: https://www.swisswuff.ch/tech/?p=7890
