Razor Blade Illusion trick
"Dave Powell's Razor Blade Illusion (With Stand) **Plays Big! Packs Flat!** EFFECT: Six stainless steel razor blades are each shown to be sharp by slicing a piece of paper. A spool of string is picked up and about a yard of it is removed and placed into the performer's mouth. The razor blades are then placed in the performer's mouth as well. But when the blades are removed, they are now threaded on the string! Made entirely of black plexiglass with silver trim. Comes complete with razor blades."
