Glamered Weapon FusionTweet
(from Starfinder Core Rulebook)
As a standard action, a weapon with the glamered fusion can be commanded to change its appearance to assume the form of another object of similar size. The weapon retains all its properties (including bulk) when disguised but does not radiate magic. Only true seeing or similar magic reveals the true nature of a glamered weapon while it is in disguise. After a glamered weapon is used to make an attack, this fusion is suppressed for 1 minute.
