This is the set of two handles and two pommels from the Fencing Sabers used in the Star Trek: The Next Generation episode 'Hallow Pursuits'.
Between Barclay and the holograms of Picard, Riker, Data, and Geordi there were at least 6 different hero sabers (unknown number of possible stunt sabers). In the fencing scenes the sabers vary in design from one another significantly. The Geordi hologram is shown using a saber with a bell guard that can fit one of these handles. It is known for sure that these handles are too long to fit the matching set of Barclay hero saber bell guards.
The matching set of pommels may have been used on the Barclay sabers but unknown.
These 'parts' of the sabers were returned to the prop studio after filming and it was from the same prop studio that these Bell Guards were directly acquired.
