Just to repeat some prior posts. The only real test is the shave test. I use the hanging hair test only as an indicator. My razors have to pass the hanging hair test before they touch a pasted strop or the plain leather strop, otherwise I am just wasting my time. If your shave is not good and restropping on plain leather does not take care of the problem then try back honing first, its simple and quick and eliminates the possibility of the most common error of over-honing. Then strop on plain leather and test shave again.
If that does not work then its back to the hones, sorry!

Since I have no experience with stainless steel razors I cannot help you there other than to say that people have said that they take quite a bit more honing than the normal carbon steel razors.
