What is "realistic" in a world where people of many professions can use magic, people often wear armor made of metals stronger than steel and things like aether and materia come into play?
People develop combat styles based on the times and context. Modern knife-fighting could have an application in Eorzea, but there are many scenarios where it wouldn't cut it (pun not intended).
What if the person you are trying to use the knife on has a spear? Good luck trying to shoulder-grab and close in to stab the spear-user. What if you tried that move on an armored Paladin? Knives by nature are side-arms in warfare. Even in the era where guns didn't exist, bigger, longer weapons were a soldier's first go-to. For Rogues and Ninja who use knives and short-blades as primary weapons, I would think the simple moves won't be enough for every foe.
