Yep, that is the link. There are many other topics of interest on that
site in addition to knifefighting however, which is why I posted the main
link.
One big concern for me are the legal ramifications of using a knife for
self defense purposes. Another concern would be the psychological
after-effects of such an encounter. Any Military or LEO folk on here who
have been involved in the loss of life in the line of duty, will probably
be able to attest to that.

There are many well respected LEO's, Martial Artists, and Military folk who
have made contributions to the site and there is also a wealth of resource
material available there.

Overall, I think it's a good site to browse through.
My opinion anyway.

Cheers
