Titleist's newest player's irons, the 712 CB andMB, designed for the golfer that doesn't need the assistance offered by larger cavity backs and prefers something both small in stature and big in workability.

The new CB and MB irons stick to those qualities that have made them such an attractive option in the past - traits such as classic lines, a compact, aesthetically pleasing profile, that familiar solid sound and feel, and most of all, the shot-shaping precision found in classic forgings. That shouldn't scare off those on the fence though, as these new forged players irons offer a modern level of playability. That comes as a result of over three decades of player research and development as well as advances in engineering and manufacturing processes.

the MB appropriately refers to the muscle back design, while CB refers to the shallow cavity back used in that model. Both sport a new back that features a faceted surface across the back that has become affectionately known as the "dog bone". The surface area, while narrow behind the impact zone, spreads wider in the heel and toe, allowing for more mass behind the impact area. This produces that solid feel expected from the traditional blade iron.

Both also make use of the popular satin finish, which reduces glare and emphasizes the toe and topline profile, which in turn makes alignment easier, further giving the player a confident feeling at address. The sole of the MB has also been refined by improving the trailing edge angle and heel relief. Together, those changes help the MB move through the turf much more effortlessly. This improved sole should make the MB a great option for players that come at the ball with a shallow angle of attack (those that pick the ball off the turf) while on the other side, the CB has a slightly wider sole that takes much more aggressive approach to turf interaction.

712 Series MB
Described by Titleist as "high performance muscle back forged irons", the 712 Series MB shares quite a bit with its slightly more forgiving sibling, the CB. For starters, it's forged of the same soft 1025 carbon steel and is covered with a modern satin chrome plating. Again, it maintains a constant blade length throughout the set and keeps offset at a minimum (though the MB does have a progressive offset as opposed to the CB which maintains constant offset). As one can expect, the appearance at address is pleasing thanks to the slim topline.

712 Series CB
The Titleist 712 Series CB irons are best described as high performance, forged cavity back irons that pack a number of improvements into a familiar looking package. The forged CB head is composed of soft 1025 carbon steel and is finished off with modern satin chrome plating. It features a number of qualities the lower handicap player usually looks for, including constant blade length throughout the set, minimal constant offset, and a slim topline. The combination of that narrow topline, along with a rounder profile result in a classic but improved modern appearance
