This is the more aggressive game changer with the .84-P head, compared to the .68P head. From RazoRock “Why did we call this razor the Game Changer? It’s really simple! This razor was produced to a standard that is superior to razors which typically costs 4-8 times the price, yet in usual RazoRock fashion we are bringing you the highest standards of quality at a price everyone can afford. The RazoRock Game Changer is built to last a lifetime, machined from marine grade billet stainless steel, the same way a Swiss watch case is machined. This is a razor you can depend on forever!”
