Which means, logically, that there has to be a difference in the head geometry between the two models. In the Type B, the blade has to be parallel with the sideway of the razor. In the Type A, it ought to be inclined somewhat. And that should be possible to see in a side-by-side comparison.
A little while ago, I found my Holy Grail Razor. Or more specifically, I found two. But to me the Grail wasn’t one razor (or two), but a type of razor. My Hole Grail Razor was the Schick Magazine Repeating Razor. And as discerning shavers know, there are three recognised types of the Schick Magazine Repeating Razor; the Type A, the Type B, and the Type C. Both of the ones I got so far are Type Bs. But today, thanks to a fellow shaver from the antipodes, my collection contains a Schick Type A as well.
