This making things sterile comes up repeatedly so must be one of the great concerns. For those for whom this is a great problem the only solution is either removing the blade from the scales or installing the blade in stainless steel scales and autoclaving the razor whenever the user thinks it needs to be sterilized or re-sterilized.

Actually the non-stainless steel and un-sterilzed scales, if removed from the blade and then reinstalled on that blade, could be a source of re-contamination. Thus that option is only the penultimate for the optimum of cleanliness. The ultimate bein only something where all parts can be washed and rinsed thoroughly and then all those pieces autoclaved. Reassembly could prove problematic if the parts have to be touched to do that, but sterile gloves could solve that issue - if the reassembly were done in a clean enviroment.

Disposable blades are really the only option for the most reliable system of assuring cleanliness and only if these are made by machine, with no human contact, then cleaned, packaged, sterilized, and opened only by the user and used by the consumer himself - only once.

So what do these clean freaks do when they sneeze? Or, heaven forbid, someone else nearby sneezes? Using the toilet must be incredibly painful.
