I'm sure I'm one of the last ones to think of this, but for those of you who haven't thought of this yet, I thought it would be a very helpful tip to pass along:
I hate pop-top cans. I just bought several cases of canned soup and every single one has those stupid pop top lids that shred my beautiful PC scraper spatulas. I was making dinner the other night and lamenting about the lids on the cans when I had an epiphany. Choirs singing, pillar of light radiating, goose bumps kind of experience (I know, I'm pathetic): I realized I could open the lids with my smooth edge can opener. I don't HAVE to use the pop top. Duh!
I'm very happy about this discovery! This has been one of my top 10 grievances about cooking. Hmmm, I guess I'd better bump up one of the top 20 into the top 10...
