pitching wedge

Wedge heads are described as stainless steel (several entries specify 431 stainless) and carbon steel (S20C in the three-wedge pack listings).

Yes. The results include right-handed wedge options and at least one three-wedge set listed for left-handed players, so both right- and left-hand orientations appear.

Shaft flexes shown include Stiff on several single-club listings, and a three-wedge set specifically notes availability in Regular or Stiff flex.

In the three-wedge pack details, 52° is identified as the gap wedge, 56° as the sand wedge, and 60° as the lob wedge.

Several wedges mention precision-milled grooves. At least one description references a maximum allowable groove width designed to help generate spin and stopping power around the greens.

The results include single wedges sold individually and multi-club packs sold as three-piece wedge sets, so both single-club and three-club pack options appear.
