Knife Through Napkin by Daryl 

A table knife visibly cuts through an ordinary cloth napkin. Instantly, the napkin is shown to be completely unharmed!
 
CONDITION NOTES:  Although the trick is new, the included cloth shows some discoloration from age and storage. However, there is still plenty of usable material for several performances. Please note that the cloth is intended to match the napkin you will use in performance. The supplied piece assumes a white napkin, but you may prefer to use a different color or style to suit your routine.
