Back from classes today and checked the post, first thanks for the complement on the correct thread section to post in. heh im not a complete idiot. As for it being pliable for streets, I just used the street term to stear clear of the stage performances of this like the ninga sword.
I have thought of ways to achieve this but it involves a magor sleight of hand with the card, and a the knife would be non gimmicked.
As for having a concealed weapon on the streets, I dont think this is a major problem, because one its self protection, Im not saying Im carrying a 10" Bowie knife, No simply an everyday pocket knife one would carry around for day to day use. And for the younger magician in public schools like jr high or high school they shouldnt carry weapons and I agree. So this would not be suited toward that setting. This is for more of an at home or outdoor area maybe. not in a school or store.
I will look up John Kennedy and see what I find. The one look and the rest is figured out didnt help me to much, I cant figure the trick by looking at a pic of a pocket knife. Ive looked at my own swiss knife and nothing triggers in my mind.
But thanks for all the info. Ill look back for more. And post if I find anything on the web, although I searched for a few hours yesterday and found this
that is pretty much as close I want to figure out.
