Once I hacked it for Undyne the Undying, and know what? Usual damage of the shoes. And answering your question, it's just what happens when you kill anyone with any other weapon. Yea, the Real Knife isn't this special.

However, good things for you - someone told me the Real Knife can kill Amalgamates and it also kills Toriel even when the attack doesn't deplete her entire health bar (glitch). About the Amalgamates, I don't know if it"s true.

Actually, the Real Knife IS stronger than the Worn Dagger, i saw a youtube video of someone hacking in a real knife and a worn dagger and doing an ALMOST complete genoicide run.

When they got to the Undying fight, Undyne the Undying took around 5,000 damage per hit instead of the usual 1,000. Bonus: Undyne the Undying's attacks only did 1 damage.
