Did the Defendo workshop today in Manhattan. Nonstop from 9:45 to 5:45. Bill Wolfe is an extraordinary guy--an entertaining (and sobering) raconteur, a compelling instructor, and possibly the most dangerous person I have ever met. The core of the workshop was grappling techniques--how to respond to an empty-hand attack from the front and take the attacker down quickly and effectively--with some defenses against knives and guns toward the end. I'd characterize the level of training as fairly hardass; I was relieved to come out of there uninjured, though quite fatigued and thoroughly bruised. Most of the material complemented the Krav Maga I've learned so far, and where the systems differ it isn't so much a contradiction as a choice among methods. I'm glad I had this additional training.
