Currently, my main EDC knife is a SOG Flash I. This little companion does a fantastic job of most everything that is relatively light duty. It is lightweight, great grip, perfect blade shape...and has a bayonet style pocket clip...so it is discrete. That said, I recently picked up a Bucklite 484 and will probably run that one for a while. Unbelievable value; Buck hit a home run with this unbelievably affordable folder.
