As long as the shadow sheath is on your person, you can Interact to draw an exact copy of the weapon from thin air. These copies retain the runes and abilities of the hidden weapon, though if you use any limited-use abilities (such as talismans or Activations with a frequency limit), they count against the weapon's normal usages. A copy disappears shortly after leaving your hand (or being used for a thrown Strike).
Immanence You can Interact to draw a weapon from the shadow sheath as a free action. Your Strikes with a weapon produced from the shadow sheath deal 2 additional spirit damage per weapon damage die, which increases to 3 per die if the target is Off Guard.
