Depends upon the amount of time one waits in between the last rinse and the first step of the repeated process.
And speaking of lathering, rinsing and repeating: That's all I ever do with my Sharpfinger. Yeah, it is stained up (patinated, I like to call it), but the looks don't matter none to how she cuts. And if you want a personal touch, have the scales replaced with something that he would like. Mine hasn't rusted one bit yet, even with the abuse it takes.
