Penetrating flight
A slightly higher CG for a strong, controlled trajectory.
Build Options
A tour-caliber forged blade with a slightly higher CG
Sub 70 Golf Β· IronsThe Sub 70 659 MB Forged Irons are the next step in Sub 70's forged blade line. A slightly higher center of gravity produces a penetrating flight with strong stopping power, and the classic top line and minimal offset give a traditional look. Each head is forged and milled from soft DT-4 steel, and an updated sole with rounded leading and trailing edges improves turf interaction for all swing types.

Why golfers choose it
A slightly higher CG for a strong, controlled trajectory.
Clean top line and minimal offset at address.
Better turf interaction for any swing or condition.
