How to flip the Rock hammer
The Rock hammer is a members-only Old School RuneScape item — “I can even smash stone with this.”. Its Grand Exchange buy limit is 40 per 4 hours. Right now it buys at 400 gp and sells at 451 gp — a net margin of 42 gp (10.5% ROI) after the 2% Grand Exchange tax of 9 gp. High alchemy yields 300 gp.
To flip it, place a buy offer near 400 gp and a sell offer near 451 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
