My first question to this forum was about first productions.
I was told they aren't worth much more than a normal model unless you are a collector, even then if it isn't labeled specifically which of the first batch it is you won't know if it's the first or last of the batch.
I have a Kershaw ener-g2 first production and although I found ^^ that out, I still treasure this thing in that I found it, it's in good condition, and overall that earns it a bit more meaning to me than the others.
