Shadow Sentry Lightsaber

Read more about these weapons at the Cartel Market Guide page on Swtorista.com.

Cartel Market weapons originally come from the Cartel Market, either through direct sale or through random chance in Cartel Packs. Almost all Cartel Market weapons are cosmetic in nature, do not have any stats attached to them by default, and can be worn by players of any level or any class as long as they can equip that type of weapon. Cartel Market weapons can sometimes be found for direct sale on the Cartel Market, but if it is not available there it can be purchased from other players on the GTN. If you can't find it on the Cartel Market which is run by the developers who rotate items in and out over time, and can't find it listed on the GTN which is made of listings created by players, you're looking for an item that is currently considered rare or uncommon, and you'll either need to keep checking back those two places, or try posting in the /trade chat or the Fleet General Chat that you are looking to buy one - but it will likely be very expensive if no one has one listed on the GTN already!
