I would like to give a critique.
The blade itself is put together pretty nicely for the most part. However, there was one small issue with it's use; the cross axle piece below the guard is a bit small. I've compared it to an official LEGO cross axle piece and found it was in fact just a hairs width thinner than the usual piece, enough to not allow it to stay connected in certain technic connections; such as the cross axle extension tube, which I planed to use to make the swords hilt. If it is at all possible, please consider widening the cross axle by a small margin, just enough to be snug within other connections, but not to the point where it's too wide to use. Please take this critique into consideration, and may it help you to develop your fine products even better.
