What it does

The Real Knife is a special weapon tied to a Determination status effect and an accessory modeled on Chara's Heart Locket. Its damage starts low and rises as the player's LV increases, so the weapon grows alongside the player's progression. A transformation becomes available through Determination, and the mod's progression system takes its design from the LOVE and LV system of Undertale.

The knife is crafted with a custom recipe from rare materials. Once made, it occupies an equipped Curios slot and grants permanent bonuses while worn, which raises the player's combat potential. The author states that the project is unofficial and not affiliated with the original creators. It runs on client and server and is published for Forge only, for 1.16.5, with the 1.2.0 beta as the latest file.
