I have a regular Sere 2000 that I've had as my EDC for a while. I love it, it's my favoutire knife. I'm a lefty and carry the Sere 2000 in my left pocket with the clip reversed. I'm debating the purchse of the Vallotton conversion. My question is to anyone who has onwned/handled the Vallotton scale release conversion - how easy would it be to operate with the left hand? That would require moving the scale back with the index finger of the left hand, as opposed to the thumb - is it possible? Or would it require feats of finger acrobatics and contortion? Thanks for your time and help.
