Well, this last few days has brought some serious progress. My brand-new Shueido sais showed up this afternoon, and I've been spending the time since doing things one-handed, while playing with one of them. They're really nice - a bit smaller through the tines than I was expecting, but a nice weight and balance.
Last night's karate class was small, likely due to the abysmally cold weather that we (and nearly everyone else) seem to be having. I got to get Tokumine no Kun vetted by Sensei to make sure I really had it down, and then we went on to the beginning of Sanchin. I hadn't quite registered how darn short Sanchin is! I'm about 1/3 of the way through in one fairly short session. Which means that unless there are unexpected complications with either this or Kusanku Sai (which I can't wait to try with the new sais), I'm pretty well on track to have all my required material down by the end of the month. The muscle clenchng is going to take some getting used to. I keep remembering to tighten one part and then noticing I've let something else fall loose. Oh well, that is why I wanted to get it down now - so that I have time to ingrain all this before I have to perform it with people beating on me.
