Blade (ship)
A blade was a structural component, found on Cardassian  and  warships, which housed the ship's warp nacelles.

When attempting to determine where the Cardassian fleet was hiding their ships in 2369, Geordi La Forge discreetly performed a quantum resonance scan of the Reklar pointing out that the ship "had some minor hull degradation along their warp nacelles. The distribution pattern [along the bladed[ indicates a recent exposure to a molecular dispersion field." ()

When the Vetar pursued the Val Jean through the plasma storms in tbe Badlands in 2371, it was hit on the port blade by a plasma streamer, disabling the ship. ()
