In the game files, the root template of this sword (UUID 5908898d-5d9e-40de-ab07-3f8fb5f0174c) actually describes a shortsword, which is also used as the basis for the Knife of the Undermountain King. In fact, the magical properties of that sword are also added to this root template (via the <Stats> tag), meaning that this item should have those properties as well, and will do so if spawned via the console. However, the weapon that's spawned in-game is not directly based on the root template but rather on a stat entry called WPN_KingsKnife which inherits properties from WPN_Longsword. This ends up making this item functionally identical to a common longsword.
Reportedly, equipping a hireling with this weapon, then dismissing and re-hiring them, turns this item into a copy of Knife of the Undermountain King.^[verify]
