As I was opening a new bag of charcoal tonight, I remembered how when I started grilling I had no idea how to open the darn things without a knife. Made a mess and ended up ripping the bag.
For those of us that didn't grow up opening bags of feed, here's a handy write-up on how it's done (not mine, just one I found). http://cheaptalk.org/2011/05/29/how-to-open-a-bag-of-charcoal/
