Thank you all for your comments. The feedback is greatly appreciated.
I'm not so sure about it being a Uchine yari. I say that only because all of the examples that I have seen are much shorter than this piece.
Geraint, I considered that it could be a repurposed yajiri. This could definitely be a possibility. I have not seen many yajiri that have a flat face like this does though. Most seem to have a center ridge that extends right to the base of the point with a six-sided base instead of eight like this example.
Rokujuro, I tried to remove the point, but I can't get it to budge in any direction. The pin the holds the ferrule in place does not extend through the nakago. I can tell this because the ferrule is loose and I can twist it slightly. The pin must be short and just extends a short way into the wood to hold the ferrule in place.
Anyone know what Smith Yasuyoshi may have been. I have been trying to find an example to match the style, but I have not had luck yet.
Thanks again for your comments. Here are some more pictures to get a better idea of scale and to show the taper in the shaft etc.
