I think patina looks good and when you hone the razor up you will get two strips of silver gleaming in the grey.

I don't know what happens to the old bone or ivory handles. Many have that crack in them. I wonder if it done by over tightening the pins and as the bone dries out when the razor is stored, it becomes more brittle and cracks.

It's a shame because they really set off well against the blade and they are so thin, light and just a perfect complement to the blade. For me at least, no modern material has come close...... yet. There are some plastics that almost match the old ivory but they are always thicker and have to be or they warp.
