Stropping, be it on a
pasted strop or plain leather will always create a micro-convexing of the bevel of some sorts. This micro-convexing is what adds to the keenness of the edge.
In my view, it is that micro-bevel that matters more than how shiney the bevel faces are made by the hyped synthetic "
hone du jour".
Having said this, I wonder whether one can truly notice a difference between a razor that is finished up to around an 8k-10k level followed by a pasted strop vs a razor that has been honed on a 7 hone progression to 30k, 50k or whatever the new Olympic record is.
I won't always use a pasted strop, but I find some razors truly benefit from additional micro-convexing, namely heavy grinds.
For centuries, razors have been finished with whatever regional finishing stone is available and pasted strops.
Less is more, ymmv and all that jazz.
