Every so often, I look at their 30-inch Nagasa online; I've been tempted, but have read some rather unflattering reviews of Cheness swords -- basically calling them poorly fitted junk. I'm glad you like yours. I don't know if they're inconsistent in their quality, or what. I don't feel technically competent to judge how "good" Japanese swords are -- sure, I can tell if one's tight or if it rattles, but I do have enough knowledge to know there's a lot more to it than that.
