The Nightblade, occasionally called an Utapaun Nightblade, was a close-quarters combat weapon forged by the inhabitants of Utapau.
An Utapaun Nightblade was included among the armaments of the N-K Necrosis droid, which was constructed from the deceased, cybernetic form of General Grievous. After a band of spacefarers annihilated the Necrosis droid within the Myyydril Caverns located on Kashyyyk, its belongings, inclusive of the Nightblade, were plundered.
