I recently acquired what I believed was a Gillette Rocket HD. I was hoping that this was going to be a go to razor since I like heavier razors like my Fatboy and the Rocket HD is apparently 71g except the British rocket HD version that I acquired is only 57g. Even a regular rocket weighs 62g so this can't really be called a Rocket HD. Can anyone shed light on this razor? It has patent pending inside and says made in England. If its not a rocket HD, anyone know what it is?
