Items of Quality bonus

Hello all

I have a player whos character has recently acquired the virtue Items of Quality via mystery initiation (yay for the volcano cult!)

This character wields a mace and wishes to forge herself a new mace, using items of quality to make it extra bashy.

However, there is no entry on the Material/form list for a mace

Can anyone tell me whether there is a published Material/form for maces and if not, what bonuses a mace might have.

I haven't seen any published ones. I'd use the shape bonuses for 'sword' as a guideline.
