Like a pin drop...

I wonder if magicians can hear the sound of an appearing metal cane. Do they think the loud sound of rapidly expanding spring steel is what magic sounds like when it's happening. I got news for you. If you can hear it, so can everyone else.

I can't hear you over the sound of how awesome I am.

There are ways to do it where it doesn't sound like a pterodactyl swooping out of the sky. There are (read: were) canes that used to be pretty damned silent but good luck finding those for a good price. You could use plastic but they usually look like crooked and wobbly. 

Personally I prefer the production out of a scarf like Shimada and Dimmare were oft to do. (If you don't know what I'm talking about Scott Cervine can show you.) 

So next time you want to fire of an appearing cane ask yourself, "Is this what magic sounds like or am I just fooling myself?" 

It's likely the latter.
