Wany to trade spyderco efficient for Persistence or Tenacious

[matt2silver]

I have a very lightly used (like new) spyderco efficient that's been lightly modded  (no back spacer and a new pm2 clip) that I'd like to trade for a spyderco persistence or tenacious in similar condition. Pics available upon request. I'm only trading because I'm a lefty and the efficient is less than ideal for us south paws. Otherwise it's a great knife!
