I have had the good fortune to own one of the initial issue Hart Steel Razors and liked it very much it was a 6/8 square.
I now have a new 7/8 square and really enjoy the razor.
To me Harts are serious no nonsense straight razors. With their resin scales they could easily be shaving gents several generations down the road.
I may be incorrect but my take is that Tim Zowada convinced the craftsman that a serious no nonsense razor was the order of the day to have a shot at success. I believe that philosophy served them well and still does. About once a year now they
will release a special series of straights through Classic Shaving. These are the razors that the craftsmen/craftsman has a chance to try something a little different in the way of shapes and scales. I am just happy with what I have and the fact that the razors are actually made in the United States of America. : )
