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 45 gp and sells at 49 gp — a net margin of 4 gp (8.9% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.

To flip it, place a buy offer near 45 gp and a sell offer near 49 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
