Wow, it's great to see such passion for the protection of what were, when they were made, rather commonplace utilitarian objects.
I did look at some video clips made by guys who look like pros before I started and I have recently found another one along the same lines which makes perfect sense to me and is what I had in mind (please tell me if you disagree):

My hone wear is very much less than the examples he shows which he says do not need regrinding, which I find most reassuring. My hone wear is a little uneven however because I was focussing too much on taking out the chips, which were concentrated at one end, than on keeping it even. I acknowledge that this was a mistake but I believe I can largely correct it by doing some more honing at the other end of the blade, and if that doesn't work out satisfactorily I have the option to regrind as in the clip. If I ruin the razor it will be a shame but I will learn from it. Other than damaging the cutting edge further, overheating when grinding is probably the greatest risk. If this happens I would have to take it apart and heat treat it - something I have done before when making tools, but I would rather not have to.
My next restoration project is a 17th Century lantern clock but I am taking this to a specialist clock repair class as it's probably worth more than a hundred times as much as my razor and I really don't want to ruin that!
