I find the shave to be much more pleasurable than the multi-bladed cartridge monstrosities, not to mention the cost is much reduced.
The main issue comes when it is time to change the blade. Have a fairly sharp (not so good for shaving but will still mess you up) blade - covered in scraped off skin and possibly blood depending on how badly I shave - to be disposed of.
Simply throwing the naked blades in the bin is not suitable. The hazard to anyone down the chain is too high. Similarly, putting the blades in the cardboard container they came out of is also not great.
I thought about the sharps bins you see in hospitals and clinics for needles and scalpels and wondered if there was a consumer version.
Small enough to sit on a shelf and enough capacity for at least a decade of shaving. Clearly marked as hazardous and easily sealed for future disposal into a suitable waste stream.
