Of vintage USA razors I would add Cattaragaus, Case, and Torrey. There are others but that is right off the top of my head. I would say for a rotation a few good solid performers would be better than a highly collectible razor like an Otto Deutsch Hans. If you have a lot of disposable income that is a different story but I would rather have 3 DD Specials than 1 Wonderedge if I was on a budget.
