I guess I am prejudice here is why.
The Blade show is 15 min from my house.
It is the largest knife show in the world and contains the most diversity as far as types of knives.
It is closely tied to the A.B.S (J.S. and M.S. judging and awards as well as the A.B.S. get together which is more than worth attending even without the show.).
It was the first knife show that I attended (Knoxville at the time.)
The guy that started it, Bruce Voyles, is from my home town (Chattanooga, TN.). Note that Bruce is no longer associated with it directly, but does organize the Spirit of Steel Show.
It was the first major knife show that I set up as a dealer.
It served as my first introduction to Custom knives.
It is my favorite weekend of the year.
... and the most important reason is that I can see more genuine friends here in one long weekend than I can at any other venue.
