I like this particular Swiss army knife because it has a bit more than the standard knife. As a botanist and biology teacher, the hand lens has been used many a time to examine detail on a moss or beetle. The saw is great for camping, as well as collecting specimens. Additionally, you have all the basic handy gadgets you need on a knife: screwdrivers, scissors, nail file, tweezers, etc, as well as your basic, essential knife blade. I've had one of these for over 25 years, and have used it on five continents and for a hundred picnics. My only complaint is that as a lefty, food/muck can get lodged in the grooves of the handle when you use the blade (e.g. cheese, bread crumbs, etc). I use the toothpick to clean it up, but a hassle nonetheless.
