Antique Knife

The Antique Knife (formerly known as Kris's Knife) is a Key Item in Deltatraveler. It appears in the inventory after defeating Sans (GG!Underfell). Despite it appearing to be a weapon, it cannot be equipped on anyone, nor can it be dropped.

In Hard Mode, the Antique Knife is not a Key Item, but instead a SLASH-Type weapon. It is found in the room where Flowey is first met, only appearing after sleeping in Toriel's home. In the Obliteration Route, the name of the Antique Knife changes to the Real Knife.

When approaching the knife, Susie will grab it and remark it as something that Kris would keep hidden, right before worrying about what may have happened to them, then reasoning that they might be ahead; since she admits she herself has no use for the Antique Knife, she gives the knife to Frisk instead.

During the Obliteration Route, when approaching the knife, she will still grab it as usual, right before Frisk steals it from her hands in the middle of her sentence. Additionally, having the Real Knife equipped will cause some dialogues to change when Frisk attempts to attack Noelle.

Trivia

• It is currently the weapon with the highest AT increase in the game, not counting unobtainable weapons such as the Test Knife.
  • However, that doesn't make it the weapon with the highest damage potential; that honor is currently held by the Clean Pan.
• Besides the name change and different cutscenes, both versions of the weapon are identical, unlike Undertale's version of the Real Knife which has a massive AT increase.
• At the end of the Obliteration Route, if Flowey is defeated while Frisk has the Real Knife equipped, he will comment on it.
• Kris uses their Antique Knife to stab Sans (GG!Underfell) in Section 3 - Hell's Forest.
  • It's not known why Kris uses other weapons to attack enemies in battle rather than their knife (which would presumably have a higher AT). However, this may be because Kris doesn't want the player to use a powerful weapon, and is intentionally concealing their knife from them so that they cannot use it in battle to kill enemies.
    • After the battle with Sans (GG!Underfell), the narration states that the knife is "too sentimental" to use in battle, which could suggest Kris is too attached to their knife and doesn't want to use it in case it gets damaged or breaks.
• The Antique Knife's sprite while on the floor is very similar to the Toy Knife.
• In the room containing the Old Tutu, the Antique Knife (and, if edited into the inventory, the Real Knife) has the same icon as the Toy Knife.
