The Black longsword is a free-to-play Old School RuneScape item — “A razor sharp longsword.”. Its Grand Exchange buy limit is 125 per 4 hours. Right now it buys at 1,005 gp and sells at 1,015 gp — a net margin of -10 gp (-1.0% ROI) after the 2% Grand Exchange tax of 20 gp. High alchemy yields 576 gp.
