Yes they do, the first 500 of a new knife say 1 of 500 on them. At least I know some have so I believe all have a first production run. Don't take my belief as certainty though.
I put myself in line on a few pre orders, honestly I am hoping they come out one at a time to soften the blows to the bank account. If the three new zt's and the 560cbcf come out at the same time I am going to be living in a box next to work as I will have no home or transportation lol.
