About the Honma TR20 B
The B is the muscle back of Honma's Tour Release TR20 family, an S20C forging with a satin finish made in Japan. It runs the weakest lofts of the three TR20 heads at the top of the set — the 3-iron is 20 degrees — but the strongest through the middle, with a 34-degree 7-iron, and its offset falls away sharply in the short irons, from 3.1 mm at the 3-iron to 1.0 mm at the 10.
