Definitely a Guisarme-Voulge.
A
guandao can be quite decorative (Sadly Guan Yu's legendary use of the weapon is almost certainly ahistorical, since the earliest references date from centuries after his death, but Bubbles would look badass in that pose):
I have no doubt Claire writes with a fountain pen in blue-black ink and has blotter paper or even sand close at hand, keeps postage stamps in her purse, and has in her possession the accoutrements necessary to close envelopes with sealing wax (even if she doesn't always use them). She owns an antique pen knife and has a supply of quills but only employs them on special occasions. It's quite likely she also carries her embossing Notary Public seal with her.
At times, I write with a
brush, though my calligraphy is not as good as it should be
, and sign the document with my personal seal*. There is pleasure in it, but for everyday use, I scribble with a ball-point like everyone else.
*Although seal is the normal translation of
图章, it is somewhat misleading, in that a
Chinese "seal" is not used with wax to seal envelopes, but with ink paste as a stamp on paper which acts as a signature.
