How to flip the Black knife
The Black knife is a members-only Old School RuneScape item — “A finely balanced throwing knife.”. Its Grand Exchange buy limit is 7,000 per 4 hours. Right now it buys at 32 gp and sells at 70 gp — a net margin of 37 gp (115.6% ROI) after the 2% Grand Exchange tax of 1 gp. High alchemy yields 11 gp.
To flip it, place a buy offer near 32 gp and a sell offer near 70 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
