Iron knife(p+)

The Iron knife(p+) 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 626 gp and sells at 300 gp — a net margin of -332 gp (-53.0% ROI) after the 2% Grand Exchange tax of 6 gp. High alchemy yields 1 gp.

To flip it, place a buy offer near 626 gp and a sell offer near 300 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
