When you have a shakey hand like mine, which has a mind of its own, all food is dangerous.
I particularly hate the sealed plastic packs that bacon, ham, salami etc. comes in. The one with the little bit on the corner that's meant to tear back, and let you peel back the whole top off easily. I've never managed it, and have to result to stabbing about with a knife, which for me, or anyone unfortunate enough to be near me, can be quite quite hazardous.
