Reman blade weapons were the hand-held blades carried by the Remans during the 24th century. (Star Trek Nemesis)
Jackal knife
This large dagger was carried by Praetor Shinzon. He attempted to use it to kill Captain Jean-Luc Picard aboard the Scimitar in 2379. (Star Trek Nemesis)
Double shadow knife
This smaller knife was also carried by Shinzon. Shinzon used it to cut his palm, so as to draw some blood for a DNA analysis. Doctor Beverly Crusher later analyzed the knife under a proton microscope to determine that Shinzon was a clone of Jean-Luc Picard. (Star Trek Nemesis)
Viceroy's knife
Shinzon's Viceroy also carried a knife, with which he wounded Captain William Riker in the arm during a fight aboard the USS Enterprise (NCC-1701-E) in 2379. (Star Trek Nemesis)
Bayonets
Reman soldiers also affixed curved, bayonet-like blades to the barrels of their disruptor rifles during their attempt to board the USS Enterprise (NCC-1701-E) in 2379. (Star Trek Nemesis)
