Mendralla wedges were introduced in the mid-1990s. The RM-I is a 52° gap wedge with 5° of bounce, the RM-III and RM-VI are 60° lob wedges, both with 5° of bounce. The II is narrow sole, the VI has a scallop sole. The RM-V has a scallop cut in the back middle of the sole to take max advantage of all playing conditions. It is labelled as a "versatile wedge". All seven feature .450" diameter fat shafts to reduce torque.
