How do we defend against kick-boxers and armed attackers?

Our self-defence requirements include scenario training against differently trained attackers, and armed assailants.  That said, I think that intensive training in weapons and in a fist-and-foot style helps a lot in comfort and expertise in those kind of scenarios.  And that takes training time, whether in one art or many. 

I have trained in ken-jitsu a little bit, and I like it.  In people who have done a lot of sword-work you can see it reflected (positively!) in their jiu-jitsu.  Similarly, as I make progress in chinese boxing, I am finding all sorts of cross-connections with jiu-jitsu.

Real combat, especially when weapons are involved, is of course extremely dangerous.  Personally, I'd rather face a kick-boxer than an attacker with a sword.
