How to flip the Iron knife
The Iron 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 30 gp and sells at 33 gp — a net margin of 3 gp (10.0% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.
To flip it, place a buy offer near 30 gp and a sell offer near 33 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
