Reman blade weapons

Reman blade weapons were the hand-held blades carried by the Remans during the 24th century. 

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.

Shinzon's Viceroy carried an identical knife while leading a boarding party aboard the USS Enterprise (NCC-1701-E), and used it to wound Captain William T. Riker in the arm, also in 2379. 

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. 

Bayonets
Reman soldiers 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.
