Thread: How sharp are DE/SE blades? And how do they sharpen them?

Use the search function and you should find a number of threads about this topic. In general, a modern coated DE blade (or SE for that matter) should not/cannot be re-honed due to the edge coatings. There are a number of devices from the early 19th century till the time they started coating blades that were made for the purpose of holding a DE while honing or stropping to extend their life. I'm sure a goodly number of these devices came into existence during the Depression when money was almost non-existent.

I have a fair share of knowledge of coatings both metallic and plastic, like teflon/pvd/cvd/plasma nitride/carbonitride/nitrocarbide/hard chrome and so on and if anything these coatings make the edges duller and not sharper, they might last a whole lot longer though. since the coatings are like 10-100X more wear resistant. But sharper (initially)?? I kinda doubt that. After a few shaves though...
