Did you use a retractable blade? If so, how did you find a retractable switchblade???

If not, how did you assure the safety of the actors? I work in a high school, so I'm not even sure we can have a real knife like that on the premesis.

Thanks for the help!

have you tried looking for prop sites online? I think thecostumer.com might sell props.
