I had asked this question in the middle of a different post, but I am still seeking answers. Does anyone know the proper way to hold an Iwasaki razor for shaving? The one reply on the other post basically said "any way you want to," but just like there is a proper way to hold a regular straight razor, there must be a proper way to hold an Iwasaki.

I just love mine - I get almost baby smooth on the first pass. It's amazing, but I would like to know the correct way to hold it as intended by the maker.

There is also some debate as to shaving with one side only versus the wedge side. Any official information on that too?

Thoughts? Resources?
