My trusty Trident. This knife was my primary EDC for well over a year, has been on numerous fishing, kayaking, and other trips, and is still in perfect condition. Only mods are removal of the manual safety, addition of a small lanyard, and a couple sharpenings.
EDC for me has changed in recent years and I now rotate through an assortment of folders, but this knife still has a prominent position in my EDC rotation.
Sog pentagon elite. Just got it back from sog -- they touched up the edge and put a new spring on it -- and it is my favourite left pocket secondary knife to my edc, which today is a zt562cf. They pair well together. And props to SOGs warranty. Very fast service and good people there!!
