Really great topic. I've carried a knife every day for 40 years and although that was mostly a locking single blade folder, I did things with those folders that they were never intended for such as twisting fence wire between the scales and using the spine as a screw driver. Then I found SAKs and multi tools and I was amazed at how much more I could do. I am still a minority around here but I have converted quite a few of my friends and associates to the usefulness of having so much capability in your pocket.
