Can for 12oz pot?

I am looking for more of a beer/soda can in 12oz to use as a pot for an alcohol stove. What I am finding is that you can not take the top off with a safety can opener of all I have seen because of the curved top.

It has been reported on this forum that the semi-circular metal hoop can be removed from side cut can openers, allowing them to be used with 12oz and 8oz soda cans.

However, I have not tried that.

If you get a standard top cutter and drill out the stop rivet so it cuts deeper, you can cut the top off a heineken can and leave the rim. You might have to go around a few times.

Hie yourself down to the local Army Navy Surplus store and ask for a P-38. It's a WW II can opener about the size of a quarter and opens anything…it's what I used to remove the top from a Heineken keg, leaving the ring intact. When you're done, put it in your UL kit. Might set you back about six bits. Happy trails!

I actually just ended up using a Del Monte sweet corn can because it has an aluminum bottom and steel sides for the 12oz thing. The big Heineken keg can was too big and the smaller cans it was too hard to get a clean cut with anything on them.
