Hey Tom. The ability to properly heat treat, and to have confidence in a heat treat process is a factor. Process plays a big part also. For example, Bark River doesn't do any pre-heat treat grinding, or drilling, or profiling. They have their blanks machined to that point. They also don't do the heat treat. That is outsourced as well so these aren't factors in their decisions. Additionally, their grinding process is much different with very different goals. The big difference is the mind of Mike Stewart, which knows more about knives, steel, and business than me. I'm blessed to call him a friend, and to be able to bounce ideas off of him, but there is no comparison when it comes to knife related knowledge.
I think a properly heat treated blade is a benefit to the customer. I don't buy that a 3V blade would benefit any customer better.
