ive held the damascus viking "GODfred" sword, absalutly beautifull but on that day i bought the miyamoto sword, at $500 when the viking was $300.
the viking sword was sharp, but dull in comparison to the katana which could have cut the Damascus viking sword in half, check em out for yourself. you can also find plenty of videos showing off the cutting power of all kinds of swords,one of my favorites is where they take the "agincourt bastard" sword from museum replicas, and chop a cinderblock into pieces.
there's no way a tiger kat would cut that sword in half. it's not truly damascus steel (no one knows how TRUE damascus steel was made, but it is made using modern pattern welding to look purty, and use a more traditional way of spreading the carbon)
paul chen's katanas are great production swords, probably the finest around, but against the REAL deal, even today, they aren't as good quality, balance or cutwise. there is no way that sword would cut through another high carbon blade.
if you took a cheap 440 stainless steel fantasy sword and hit it edge on edge, providing the thing doesn't fall apart first, then perhaps you would cut through it. i doubt any respecting sword owner would do it though, it would permanently damage your blade.
but the thing is, swords just can't cut through metal, it's just too hard, they were never designed to do it. take your tiger and hack into a big tree, you'll probably damage it! swords are designed to cut flesh. plate armour was designed to protect from these. this wasn't just a bit of metal, it was a skillfully forged high carbon steel plate with ridges and angles for strength, which also gave further protecting from slashes.
even the sharpest sword would glance off. by the high of the plate mail perios, where the only exposed parts of the plate are covered in thick chain (which is also highly effective at protecting against slashes) some european swords had lost their edge altogether, with just a long thin sharp blade with an almost square cross section to punch right through armour (and even with these things is was bloody hard).
simple fact is though, that these armoured knights were the elite. the most successful armies were those with cheap effective troops who could kill any enemy quickly. i'm instantly reminded by the battle of crecy, where 30-40000 fully armoured french knights were massacred by an english force of 8000, primarily longbowmen. english losses were about 200 men. the entire french force was obliterated. often the best solution to a problem is the simplest...
the evolution of the european sword is quite interesting. a guy called oakeshott wrote a book describing the changes and influences in sword design, relative to the armour of the period.
