Yes,
If you are going to try it that way, do all of your grinding bare handed to feel the heat. Remember, by the time you feel the heat, it may be too hot, and lost it's temper. If the steel turns colors, it's too late.
I dont like doing it this way. It's to risky, but I know you may have to. Just take your time and dip in the water often. Especially watch it close as the blade gets thin. I cant say it enough. Lin
