There is another question involved in this: Are there signs which are not glyphs? Signs which need a 'pole'? If there are, then I must add yet another page to my glyph catalogue, a special page for such signs.

 

If I must have such a page, I thought, then I should start with the 'closed fist', e.g. in (Pa2-15--16):

 

But parallel glyphs (Ha2-21--22)

 

 

made me think that it wasn't a closed fist at all, because an extra 'fist' seemed to be dangling from the elbow of the character at right.

 

Later I have come to believe that what looks like a fist is meant to be a simplified GD12.
