A couple things. I am not familiar with either make so I can not speak on their behalf. The following is only my undereducated opinion.
The bevels, while unique and very hard to do, don’t look like anything out of the realm of possibilities. The fullers on the other hand would be exceptionally difficult to pull off. Again not knowing either maker, I would assume neither used a mill and most likely forged the beginning portion, then most likely used some unique tooling, probably purpose built, for the rough work, then I can only assume a tremendous amount of hand work and detailing went into both blades.
I don’t have any reference for you level of skill and collection of tools. Therefore I am making some assumptions. I’m guessing you are a relative beginner. Bearing that that is my impression l, I would suggest a couple things and make one statement.
Statement first. There really are no shortcuts, even with complex multi axis machines a build like this finished to that level is remarkable. Time really is the only reliable teacher.
Take it slow, learn the basics. Understand basic design principles, basic techniques, and expand on those. There are a few steps that may shorten the curve, such as expert tutelage but start at the bottom.
Don’t be in a hurry. Knives like those even with extraordinary talent and skills can take years to finish. That said I can feel fairly certain that both of those makers had made hundreds of not thousands of knives before those. And most likely several with separate aspects of those builds before they combined them all.
I sincerely hope I’m not dissuading you from giving it a go. They are lofty goals, but not unattainable. You just need to start slow.
