Both of you failed, you have to solve it with one STROKE of the knife, and stabbing isn't a stroke, so the answer is clearly to slit both of their throats with a single stroke of the knife 😁🔪
@Basic_human the legal solution is to slice both apples at a 3rd so you get two 2/3 of an apple and two 1/3. you give each friend a total of 2/3 of an apple.
Ummm have you never cut anything in your life before..? You can cut a third off an apple without cutting the other thirds off of it. As to how you cut two thirds in one stroke, as you can see from the photo the knife is big enough and long enough to slice both apples at once.
