I don't know this for a fact, but I think the older stuff by CS was better. I believe they are now just having things made by the lowest bidder in China.
I own a cutass, a viking sword, and english broadsword. I don't cut that much with them, because I have much better tools for it, but I have cut a little with them. Overall, I think they were worth the money, but not more.
As for the Katanas, Jason Knight had one of the warior series, (maybe an older one) and we tested it to destruction. We cut up live trees with it without any trouble at all. As stated above, it did seem a little heavy, but that is perhaps why it actually held up to the abuse we gave it. We eventually completely destroyed it by chopping up a steel wood stove. The handle shattered, and eventually came completely off. the blade edge was badly dented up, but it never broke, and it never bent. In truth, I was impressed with it's toughness. I may invoke the wrath of the gods for this, but in my opinion Katanas are just not meant for serious chopping. They are designed and built for brief combat against unarmored flesh, and for that purpose they are excellent.
That said, I think I would agree with the above posters, and go with the Chen. More for the money.
