You don't have to forge ANY type of steel, and you can use stock removal on ANY type of steel. although the reverse is not correct. IT all boils down to the makers idea of what he thinks or what method he was taught. Some will say forging is the best! Some will say stock removal is the only way to go. I will say that forging is a nice way to go, when using simple carbon steel, and when using high alloy stainless steels, stock removal is the only method to use { most of the time} It's not really that confusing, and I have to be careful of how I say things or I'll have the entire Blade Forum crew on my tail.But in my opinion, what I've said is the simplest explaination of a complex relm of idea's and theory's.
Good Luck!!
