What to do with a ton of used blades?

[DanOK]

I put them in a old prescription bottle with a child proof cap. When it looks full I throw it tin the garage can.

I got it!
Make a door curtain.

That is all sorts of horrifying...

I've got an empty 16 oz tub of Clubman hair gel that I use to put my blades in. I figure when it's full (I'll be about 65) I'll just toss it into a recycle bin. Gives me about 30 years to come up with a better idea.
