Very nice work. I really like the O-kissaki and its crisp yokote. Very well done.
My only comment would be that the koshirae should be matching. The koi-guchi, habaki, tsuba, and kashira are matched with a nice stippled pattern. The fuchi is grooved, and seems to fight the others. This draws the eye away from the overall beauty of the knife.
Compare the above to a beautiful woman with perfect figure. She has a spot of chocolate on her nose from a candy bar she is eating in a very sexy way. All you will see is the dark spot that does not seem right - and ignore the fact that everything else is perfect.
