So I was following a tutorial to model a katana, all well and good, until this part. First; the top end of the blade, which was extruded from the rest of it originally, seems to shape itself differently to the rest of the blade. As indicated by the left arrow, I can't seem to get maya to treat the blade tip and end to be one, smooth, shape. As for the second arrow... well, that's a bit of a gaping whole, but for some reason maya won't let me add edge loops to that area!

For reference, this is the tutorial I am following: https://cgi.tutsplus.com/tutorials/mo...art-1--cg-2631

This issue occurs from about stage 56 onwards.
