One of my favorites was a couple of small touch knives from Olfa. I keep one on my keychain to open boxes when I am volunteering at the food shelf.

I wish they would stop with the mugs, wine glasses, water bottles, etc. Doesn't everyone already have enough of those? And I for one do not want advertising on my wine glass.
