Most Expensive Sticks: Maruman 2007 Majesty Prestigio Irons
This Japanese company claims to have developed the first metal wood (TaylorMade would disagree), but they can certainly claim the priciest set of irons you've never heard of. Their flagship range is the Majestic Series, which features the Prestigio men's iron set, made from a combination of stainless and maraging steel that has been strengthened from the previous model to minimize energy loss at impact. And since you're spending so much, you might as well get the 2007 Majesty Prestigio Driver ($2,499) and a Fairway Wood ($1,750).
