Sword handle and pommel

I have modeled a mesh sword it is all one object. I connected the pommel to the handle using Ctrl J but there are no edges connecting the vertices of the sword handle and pommel together is there anything wrong with that?

Here is my blend file

No. Although you probably didn’t mean to join these too

To separate those back to their own object(s): edit mode, select one mesh part and ctrl+L to select the rest, or hover mouse cursor over one and press L to select linked, P to separate. Could also give the objects more meaningful name, ctrl+click on the outliner to rename.

The mesh has inconsistent face normals (face directions). Edit mode, select all, ctrl+N to make normals consistent and pointing outside.
