Ignore me, I'm a total newb...however I greatly respect Tai Goo's work as well as Kevin Cashen, Daniel Winkler and many of the other "ABS side" guys on this thread. I can't help but ask though as I'm reading all of these replies if the "science guys" and the "art guys" are just not talking past each other about different aspects of this craft.
It seems to me that knowing how something happens doesn't necessarily explain what occurs. It is, obviously, possible to know what happens to steel of various chemical make ups when particular heat treat methods and other variables are applied. You can also, obviously, know what the particular properties of a certain design or style might do by testing, even in a so called "pseudo-scientific" method. I think even the "art" guys would admit that you aren't going to make a 2" dagger and call it a camp/chopper. All of that, and more though, is irrelevant to the reality that a knife is more than the sum of its components.
If that were not true, then a manufacturer who had precision CNC machinery and following the results of scientific measurement, test and metallurgy could repeatably and fairly easily create the perfect knife for any given situation. If that were true, then why would any of you who desire to make a perfect knife continue in a way that's bound to fall short? We all know that's not the case. So if that's not the case then what's the argument about? One side is arguing that it IS possible to know scientifically and objectively what is happening during each portion of the building of a knife. The other side is arguing that none of that matters to the building of a knife. The end result is that both are true, in as much as it only matters to the maker of the knife if he has made what he desired and is pleased with the result.
It seems the non-argument is about who's right in how they view their view of what a knife is. Unfortunately for everyone, that's an argument that can never be won. What we all want in a knife is, at the end of the day, totally subjective. I think that's the "box" Tai wants to stay out of, however I don't think that the ABS is the "box" that he and Ed Fowler believe it to be. You only get stuck in a box if you climb in it first.
