Also, MA page 122 expands the details:

"...Any weapon that also works with a non-fencing skill –
meaning any skill other than Main-Gauche, Rapier, Saber,
or Smallsword – has a mass distribution that lets it parry
flails at the standard -4. Examples include the short staff,
which can use the Smallsword skill or the Shortsword skill
(treat it as a baton), and any rapier heavy enough to use with
the Broadsword skill."
