I've allways wondered what it is with asian ma's (or weasterns impression of eastern-ma that leaves us to believe) that things were so specific and specialized? The martial art of wielding the nunchaku, the martial art of the staff, the martial art of drawing the sword, top ten deadly kung fu weapons, the circus-tent-peg-hammer-super-club-weapon, the beheading-frizbee... Constructing swords specifically with the aim of horselegs? How specialized does it need to be? When we do test-cutting on pigs, and cattle on Medieval shows, etc, anything can cut a horseleg, from a small onehander, upwards. I'm pretty sure horselegs have been cut a lot of times during mankinds flirt with metallurgy, but I have problems believing that swords were designed just with that in mind; "Oh quick, come with the anti-horseleg-sword... oh, no, he turned, now I need the anti-incoming-missile-shield... oh wait, here comes a lance, give me the anti-incoming-lance-shield instead!" I'm not trying to make fun of anybody, and this is perhaps off topic, but I am convinced that when asians fought eachother in distant past, they followed consistant teaching and systems that could be applied outside the box. If they had swords, they were probably capable of beeing quite flexible in their use, and the only way to know how, is to play with them (unless we have manuals that tells us how they were used). Specialized blades exists in Europe as well, you have the excecutioner-swords and proseccion swords, but what they have in common is that they are not meant for combat.
