Hmmm, "help wanted, left-handed hand model."
The photo was given to me by Yuuki-Cha, but it is from the Tokoname site. The most common method and most natural is #2, like shaking hands with your kyusu. I also will use this with thumb on the nob more times than not. I have used #1 for a short handled kyusu, and less often #3.
#4 is obviously 2 handed for chickens!!!
And note the hole position on the lids, pointing towards the spout, the way it was meant to be.
