I have seen a tool that helps drain the last of the fuel out of your isobutane fuel canister, and then pierce it to make it easy to crush. It's a simple little gadget that looks like a can opener. What is this tool called and/or where can I buy it online?

This (Jetboil Crunchit Recycling Tool) was found by googling "crush isobutane fuel can" and reading this second result (right below the outoors.SE question) for the link.

Thanks. Should the link ever become invalid, the answer to the question is Jetboil Crunchit Recycling Tool – Joe Dec 3 '12 at 0:47

Cheaper and easier solution.

Attach your stove thingy (In my case, a pocket rocket). Open all the way and invert the can (away from flame sources obviously).

Use a cheap and old fashioned church key to puncture the side.

Total cost, approx. $0.50.
