I knew you'd say that. I've had all my Enduras for almost two decades... I have about 5, and the Spydy serrations always performed unlike any other serration I had ever used so I stuck with it back then. If I were to by new, it would be a ZDP189 Endura straight.
Kershaw Ken Onion Blur. I have another Blur that is half serrated that I have had for probably 10 years. I need to fix the chips on the tip...I like to use it as a screwdriver. Love the assisted opening and Kershaw's service is top notch. Bend a clip, give them a call and a new one is shipped out with screws in a few days. The other blade I have had lost about 1/4" of the tip, sent it back and they reground the blade to but a new tip on it, replaced the assisted opening spring, and installed a new clip for free. Only took about 3 weeks total turnaround too.
