Depends on the steel but stropping if done right will not hurt the edge and only refine it further, like honing there is a point where the edge and the surface meet and that is as far as you can go, but it will not hurt it, again if done correctly. Normal for me is 30/60 prior to shaving and 5-10 on linen and leather duri,ng the shave, depending on how the blade feels on the skin. To me that is the most important thing in determining whether to strop more or less. An acomplished Str8 shaver should be able to feel almost every part of the edge on the face from the toe to the heal, and determine if the edge is keen to their liking.
With multiple razors and shaving once a day, it is not so critical, unless you are a stickler, Like me LOL, but in the shop where using the same edge literally 100's of passes a week, the stropping both before and after, as well as after each pass becomes critical, as otherwise you would be honing all the time, and the keenest, smoothest edge is also critical for customer comfort as you are taking the same razor, or a few and shaving over all types of different face surfaces, and all sorts of different tensile strength whiskers, diameter, thickness, resistance, and so forth
Just my 2 cents, Thanks
