Vibration dampening is a huge theme with Cobra’s AMP Forged irons.
In the cavity behind the hitting area, the irons contain a shock-absorbing aluminum medallion and a separate insert, both made of thermoplastic rubber.
They also have tungsten inserts in the sole to promote an optimal trajectory. MSRP is $899.99 (eight irons, steel shafts); stock shaft is the KBS Tour.
Forged irons have made a dramatic comeback. Only a few years ago, most irons were made of investment-cast stainless steel. Now we see forged irons, made of soft carbon steel, in the club lineup of every major club manufacturer.
In general, these irons appeal to low-handicap players, although companies such as Cobra are making a pitch to golfers of average ability who probably are planning on improvement.
