Lost Knife Hideout is a cave located in The Elder Scrolls V: Skyrim. It is a sublocation to Lost Knife Cave, and is one of the strongholds of the Silver Hand. If the Companions quest-line hasn't been started, bandits occupy it instead. Its name is also the name used within the map marker for the entire location.
The hideout is an area accessed after walking up through the cave's system of large caverns arranged around a large shallow subterranean lake inside the mountain. Tanning racks and grindstones are near the living quarters in addition to a large, tavern-like room full of food, mead and hunting trophies. A large arena area littered with dead bandits and animals is in the deepest point in the cave. On lower difficulties a bandit thug will spawn in the arena.
