This is an iron-handled version of a scholar’s brush with a sharpened handle.
Benefit: Though it does little damage, it is easily concealed (the wielder gets a +2 bonus on Sleight of Hand skill checks made to conceal a iron brush on her body) and can be used as a jabbing weapon or thrown short distances.
