Non-cooperative tanto dori
As you can see, grabbing the wrist and trying to to grapple with a knife wielding assailant is not the brightest of idea, IMO. To me, it is very risky, as the chances of getting cuts is just to prohibitive.
I have some thoughts wrt to better ways to deal with such scenario (empty hand wise), but I reserve my judgement till I hear more opinion from other posters.
Kali people like Mike Gallagher, would you like to comment?
