So you're the one... I wasn't quick enough : already "sold" when I read Nordic's newsletter ! As far as I know, Dietmar made quite a few of them. I already saw these mini knives on the after market (especially on european shows). I would say he made a dozen, or something like this. Maybe you could get in touch with Manfred Melzer from Ars Cultri in Germany. Or I can e-mail you Dietmar's e-mail adress if you wish.
Edit : already saw, but never at this price... Congratulations !
