I was thinking, though, how much resistance two thumbs could give if the recipient of the kubotan hold strongly, sharply tries to cut through them with his arm to get free.
You are right again on the flaw in the hold. However, you can roll/turn with the opponent as you put the kubotan on him, to get a good angle: one that is difficult to resist. It would take a lot of samurai fortitude to pull out of a well applied #2 wrist lock.
To escape: Forward pressure, pushing toward the wider part of your arm, and doing it before the squeeze is fully applied, is a good idea.
No weapon is unbeatable.
Tak Kubota, the American Japanese who popularized the weapon, liked to refer to it as "a tool of attitude adjustment." I will not demand of the weapon more than that. I will criticize it on John Wang's terms, though, There is no finishing technique. Oh, you could kill a man with a kubotan if you thought about how to do it long enough, but you can do the same with most anything.
I define internal martial art as unusual muscle recruitment and leave it at that. If my definition is incomplete, at least it is correct so far as it goes.
