Great question. I've been wondering the same thing. The only true lefty knife I own is the Kershaw Mini-Task lefty. I really like it, but need something a little bigger. I was thinking BM makes a lot of good lefty knives, not to mention the Axis locks.
Then again, I'd really like to go custom. Like one maker told me, "I don't have any left handed models with me, but give me a call and I can put one together for you...that's why they call it custom."
What do you guys carry?

BTW, I also really like my Spyderco Wegner, and Gerber EZ-Out ATS-34.
