Hi Kevin!
Their history is pretty long. I think, it´s one of the most traditional knife companies in Germany.
About CNC laser cutting, I don´t know if it´s good or not, too. But I think these kind of knives are made for a long term of use. Though nowadays they are more collectors knives. I just made the joke about costumizing my own one... pretty heavy prize.
About the used steel, I think a little mail to Puma could help.
Kind regards
Andi
