Chisel

The Chisel is a free-to-play Old School RuneScape item — “Good for detailed Crafting.”. Its Grand Exchange buy limit is 40 per 4 hours. Right now it buys at 121 gp and sells at 139 gp — a net margin of 18 gp (14.9% ROI) after the 2% Grand Exchange tax. High alchemy yields 1 gp.

To flip it, place a buy offer near 121 gp and a sell offer near 139 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
