Now that I've had a week to play with them, my EDC favorite is the Kershaw Speed Bump. It is easy to deploy and has a safety (which I only use when I am concealing the knife and not using the pocket clip). The strange shaped blade seems to work fine for opening letters and packages and cutting line. I really like this knife a lot. The HEAT is good, too. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
