I was going to guess the Dodo but now it looks like I am too late. I used to carry a Para. I work on elevators so I have to strip wires and open boxes ect as well.
I have carried several knives at work trying to find one that works best.
I started out with a Kershaw PE Vapor (worked well actually for the price). Since then I have carried:
Spyderco:
Endura PE (Endura II), CE and SE, Police SS PE, Delica CE, Para PE, Harpy SE, Dodo PE, Rescue CE and PE, Renegade CE, and one or two others.
I have tried many of them and some worked well (Para, Enduras) and some not as well for what I used them for (Harpy, Rescue, Dodo). I have also carried a couple of other brands like CRKT M-16s. I think they make a decent cheap knife for work BTW. What I carry at work now is my blue CE Benchmade 921 Switchback!
I know, I know, I am a big Spyderco fan and I carry a Benchmade! I only have two BMs but I have about 30 Spydercos. I have had about another 60 Spydercos that I have traded off. I have owned maybe 6-7 Benchamdes in my life and close to 100 Spydercos. It is jus that the 921 Switchback is almost perfect for what I use a knife for at work. I do have a couple of Spydercos that would probably work just as well (Centofante II, R-2, G-10 Police) but I don't want to risk them at work.
It may seem strange to carry a $100+ BM over a Centofante II that I got for $65 because I don't want to risk it but that is how I feel.
