About Iron knife

The Iron knife is a members-only weapon in Old School RuneScape.

"A finely balanced throwing knife"

Over the last 30 days it traded between 38 and 43 gp on the Grand Exchange, averaging 40 gp. About 250,998 units changed hands per day. The price is up 2.6% across that window. The Grand Exchange buy limit is 7,000 every 4 hours.

Casting High Level Alchemy returns 1 gp, which is 97.5% below the 30-day average price, so alching a bought one loses money.
