I can not comment on the class.
However, the Cold Steel largest Voyager, in plain edge and clip point is my favorite large pocket knife, and the one I carry and use every day and have for several years since they came out. I have used two of them soooo much that I sharpened the blade down to about half width... I use it on anything and everything; like a carpenter does a hammer, and I treat it no better than a carpenter treats a hammer.
The knife is acceptable steel for an acceptable price. It is very light, very thin, very strong, and takes a good edge with a modest effort. The handle is easy to grip, the lock is good, and the handle is not much larger than the blade, an important design element for me. The largest Voyagers have been discontinued recently, so I purchased two extra ones, just in case it remains my favorite knife for the rest of my life.
As far as knife fighting, I learned enough from working with migrant workers, who had knife fights weekly, that I KNOW for a fact that I will do anything to stay out of a knife fight.
I also learned from living in Washington DC, near the Civic Center, where they have World Championship, Martial Arts competitions more than once a month... I learned that the street thugs had great fun beating the crap out of the world champions of all styles of martial arts... just for fun. And, they didn't even consider that they needed a knife. Never heard of them cutting a world class martial artist; however they left dozens of them on the sidewalk who went to the hospital. Then they would go to the championships with buddies to show the injured world champion they had beat the crap out of...
Not me... I don't want to fight anyone who has made a life, however short it may be, out of street fighting. The ammount of pain they are used to getting and giving and the techniques they use and have used on them... are not what I want to be involved in... no matter what course and no matter how expert the instructor is.
My big Cold Steel knife is a TOOL.
