The curve of arab tulwar is close to 90 degree ! it isn ' t fit for chinese habit . i think the curve of cavalry dao can ' t be less than 120 degress 阿拉伯弯刀的弧度接近90度了!不适合中原的习惯。我个人认为马刀弧度最多不能少于120度角。

Maybe i ' m ignorant . so far all the long zang dao i saw are the shape of straight back and scabbard , whose the head is round shape . while this scabbard head should be of tulwar , and the fitting is quite different from zang dao shape . whether it ' s zang ware needs research 可能在下孤陋寡闻,迄今为止能见到的长藏刀皆为直背刀型,鞘为也为直形,鞘头为剑式圆形,而此鞘头应是弯刀刀鞘的装具也大异于一般的藏刀制式,是否藏器值得再推敲。
