Every face is a "Makee Learnee" with the Kamisori. I like to use mine...once I got them honed.
Go slowly and consider that you have a razorblade on a stick. That was true before the Japanese were known and some blade makers made travel sets with a similar though cruder final result.
Kamisori are a combination of no iron ore available but black sand; Art, and tradition.
A very Zen type of blade...and it can bite!
Take your time and enjoy the process. I've become a better straight shaver with some of the lessons they taught me.
