Kenpo Karate 401 by Lee Wedlake
Heh - I need t catch up on those...I was leafing through 201 today, but then moved on the "Ninja Weapons - chain and shuriken", previously titled Spike and Chain I believe. It is on the Masaki-ryu's Manriki-Gusari.
There is a nice Kyusho chart in it, as well as plans for making your own manrikigusari.
