To: Tsuchiya - I'm glad I was able to help again! Yup, there's definitely a lot more to using a knife. And you're right, it's best not to incorporate any tool or weapon into your fighting style until you know exactly how to use it. Unfortunately, a lot of folks never realize that there is a difference between how to use a sword vs. how to use a knife....... The last article is one of my favorites too. It tells it like it is; pulls no punches. Your Grandmaster is wise indeed! He understands the importance of taking the modern world into account. I can understand the techniques being fairly brutal. Sometimes you have to be brutal; otherwise, you don't make it home at night! ......... I can understand not wanting to overload your brain. But, in case you run out of good, reading material; check out this site - www.donrearic.com Two articles in particular. 1) "Street Reality and Martial Arts" (Under the topic, "Gear and Training.") and 2) "Modern Metsubushi Concepts" ("Exotic Weapons" topic). The 2nd article relates directly to the Art that you are studying! .......... Oh and don't worry, I don't want you to get overwhelmed with all these articles. I promise I won't post anymore links for a couple of days! ;)
