I have every other achievement in Fruit nNinja and all I can find on it is the description the game gives you, which is "You are relentless in your pursuit of perfection!"

You can get this achievement by going into Classic mode, slicing one fruit, and then restarting. Do this 3 times in a row, and after the third restart, you should get the achievement.
I found this information here, but I did try it out and confirmed it on the iPhone version.
