So what is your background and experience with swords?
I'm not the one claiming to be able to tell what's good and what isn't.
But if I were, I'd point out that although it's not something I currently practice, I've made blades from small daggers to bastard swords from raw steel. I've made a few (6-8") pattern welded blades.
I would say that my understanding of the theory outstripped my physical abilities when it came to forging steel, I could never develop the perfect consistency of technique required to produce the best blades.
Of course, given the ripples in the blade shown in your YouTube examples, neither can the armoury you're defining as "good"...
There's not a lot of opportunity to train with or study European sword in the USA. I was lucky enough to spend 7 years in Europe in my younger days, and did get a chance to at least examine and handle a number of period weapons.
I've studied the training manuals of people like Agrippa, Silver, et al. Given the lack of places in the US to get period training, I fought in the SCA. Primarily rapier. I always used the Schlager, as it provided the closest replication of the handling characteristics of a period rapier. I was considered fairly skilled, and at various times won pretty much every major tourney in the Outlands and Ansteorra.
So I'm not a world renowned expert by any means, but I do have some idea what I'm talking about.
Now, you will notice that unlike you, I provide a direct answer to a direct question. Your reputation might improve if you learn to do the same...
