I started with a delica 3 combo edge. 13 years and 13 spyderco knives latter it still is my main EDC. delcia 4, endura 4, native, centophane, dragonfly, rescue, paramilitary, military, ladybug, stretch II, Pacific salt, pacific salt 1.
I found out the lock-backs and carry tip up carry knives work for me the best. My EDC carry is my back pocket no clip. knives that are 4" or less in lenght or 2 oz. or less in weight and with FRN handles are what I end up carrying the most. My big carry knife is my Stretch II FRN. Sad to say I've run out of knives to buy. Sorry Sal.
BTW I sent my delica 3 back to spyderco to remove the chips in the blade edge and re do the broken tip like a delica 4 and it is as good as new.
