A HANDMADE knife is possible. Wootz, Pulad, crucible steel or tamehagane are all examples of steel created from ore. Yoshindo Yoshihara, Ric Furrer, J.D. Smith and Al Pendray are have all, at one point or another done/still do this.
The billets are created from ore, forged to shape, and sharpened.
The semantics are NOT important for the vast majority of us, but they are important for beginning collectors or advanced collectors. Beginners need to know what is out there, and advanced collectors tend to have very specific tastes/requirements.
I don't believe that the majority of the hand CRAFTED knives out there are anything more or less than that.
Sole authorship, as stated above is very nice, and appealing on an emotional level, but that has honestly more to do with the maker than collector. Hand crafted screws are very cool, but how much time does it add to the crafting of the knife?
Full disclosure is ideal for the betterment of everyone, but if a maker chooses to make their own screws, pivots and bushings, they should not look down upon another maker who does not choose this path, nor should the collector.
CNC machines have a nice place in the shop that can afford them. RJ Martin recently crafted the Havoc, with a 3 bevel grind, and that would probably not be possible by hand, at least not to that level of precision.
Custom made knives are just that. They are custom, either to the collector/maker, starting with drawings, or something that the maker cooked up on their own.
What IS important, crucially so, is the communication between maker and collector. Makers MUST communicate HOW their knives are made(who made the damascus, who did the heat treat, who did what to what), and the collector MUST ask, and be educated to do so.
It is these differences that educate us all. Wolfe Loerchner uses files and sandpaper to make his knives, most makers use whatever equipment that they can, and some use as much machinery as possible.
It is very, very important for us to know if we have a one of one knife(ie, all Russ Andrews bowies are very different, same with Nick Wheeler) or we have an example of one of many(ie R.J. Martin Devestator, Darrel Ralph Gunhammer). It is important to have this knowledge so we can understand what we like and desire(as collectors).
A Tom Mayo TNT and a Chris Reeve Sebenza could look VERY similar to a newbie. Chris has a number of employees, and state of the art machinery to produce his lovely precision PRODUCTION knives. That is what they are, but STILL require a great deal of hand work to produce. Tom works in his shop, alone, AFAIK, with very few basic machines, turning out HAND CRAFTED knives, 1 at a time. This is a good comparison, I think, what about the rest of you?
It is important to determine what qualities are most valuable to you, and then figure out where the intrinsic value lies/meets with personal economic value. It takes a long time to understand.
