I'm not sure I follow, Tim.

I understand what you are saying about Takeda's knives. I know most knives on CKTG and other major JK knife retailers go through the process you are describing but there are knife making techniques where the named craftsman does not do any heating and shaping of the blade. Are you referring to steel production processes where knife blanks are rolled out as forging?

I think this article will clear up anything: https://knifesteelnerds.com/2019/07/22/ ... al-knives/

Basically what I am saying is forging is part of the process of creating the steel that all knife makers use, regardless if they forge the knife to shape or grind it to shape. e.g. - A stock removal maker is starting with an already forged pc of steel same as a maker who is forging the steel to shape. Even CPM steel is forged into its final shape before being worked by a knife maker.

I always thought CPM was more of a cast process.
