How to remove the top of an aluminum can (fast) 

My pleasure!

Thanks for your comment. Yes, I have experimented with different speeds and different grit sandpaper. It seems that medium-high speed and 80 grit sandpaper is a good combination. Thanks again for your interest.

My canopener opened like 10 and then it stopped cutting anymore. That's why. My can opener is like a really old model, really tough and good and I almost ruined it. the new hand canopeners can't even cut the lids off like my old model, so I need a new method. I probably won't use this method since I don't have a giant vice grip , or a flat sander disk to use. i'll probably just use the sandpaper method from the previous video. but this looks like you could get through a bunch of cans at once.
