Most players stick to the main manufacturers when it comes to golf equipment. But every now and then, a boutique company will try to enter the market: Meet New Level Golf. They are most known for Ryan Moore's recent switch over to them on Tour.
From NLG's website:
The new PF-1 irons are designed exclusively for elite ball strikers that demand more from their irons. The compact size, thin topline, traditional shape, and negligible offset make them the perfect tool for top amateurs and professionals alike. The forged one-piece construction and CNC milled finishing give you a club with perfect face flatness and grooves for better consistency with each iron throughout the set.
