If a razor with an etching is put on a buffer with polishing pastes, or thrown in a tumbler with polishing media it might take the etching down some. Rubbing maas or semichrome &tc on it with a paper towel wouldn't take it off in 100 years IME. I like jimps too, but plenty of razors don't have them. I don't think any of the dubl duck razors had jimps. So 'good' razors might or might not have them.
