Can stainless steel blades actually be recycled? Sure, tin cans and smashed up cars, but tiny stainless DE blades?
If it's iron-based and it melts, it's recyclable.
In the US are there no blades in container with blade-grave on the back?

Yes! I added such a picture to the wiki page on blade disposal. The blade box is from Feather.
