Hey Michael,
Just catching up to this thread, so I'll throw my two cent's worth into it ...
As regards the discounted swords, it depends on what you're looking for, and what the price is. If he has them at 40% off of his marked price but you can still buy it cheaper on the internet, then I wouldn't think it was too great of a deal. The biggest problem that I've come across in any of the Chinese made "Japanese style" swords, is that the quality of any individual sword can vary greatly from one right next to it. The way they are made, there are a number of people working in a factory putting these together. If the person doing the final shaping and polish is good at it, then you'll get a decently shaped sword. Likewise, if the person wrapping the handle knows what he's doing, then you'll get a decently tight wrap. The problem is getting a sword where all of the people working on it were good at their jobs. There are far less of those out there. Being able to handle the sword in person before buying it can help eliminate the guesswork that's usually involved with it. I'm sure you can find lots of information on both Ryumon and Musashi if you search for them over on Swordforum.
Yes, this is why I am generally skeptical of something coming out of China. Many are just horrendous junk, but once in a while comes along something a bit better. But I am a disbeliever in general and it takes a bit to convince me. Hence my thread here...
As regards high end blades bending, yes they will. Due to the nature of Japanese swords, they are actually meant to bend if you seriously mess up. However, proper training will tend to eliminate that problem, and higher quality swords tend to have much better heat treatment, which means that they don't bend as easily. On a slightly different note, whacking tree branches with a katana is foolish. They are designed to cut flesh, not foliage. Machete or khukri are more properly designed to cut tree limbs without damaging the sword.
Yes, understood, and I was not endorsing cutting heavy tree limbs with a katana style weapon. That was just the test done on that particular blade to see how well it would hold up, and that brought up the issue of the blade bending and made me go "hmmm....."
As regards 5160 steel, it is good for European style blades, not katana, due to its lower carbon content which will not allow it to harden as much as needed. European style blades are not generally as sharp as katana, and they will not hold the edge as long. This is because of the method wherein they are used. Katana are designed to be very sharp due to the hardness of the edge. Don't mean to argue with Mr. Dunn, but lower 60's on the Rockwell hardness range is where I've been told the edge on a Japanese sword should be. Western swords have edges in the mid 50's. However, it is the softness of the back of the blade (mid to upper 40's) which allows the edge to be so hard and not crack.
As far as I'm aware, there's only one sword that combines the hardness of a traditional katana edge with a spring back rather than a soft back. That's Howard Clark's L6 bainite blades. He's only able to do that because of the intricate cryogenic hardening regimen he follows.
Ah-ha. A light just went on. The difference between the soft back and the spring back, that accounts for the bending, but it must be done that way to support the superhard edge. With the exception of Mr. Clark's bainite blades. Do you have any specific info or a website I could go to check out his stuff? Thanks!
