A paintbrush having at least one protuberance arranged so that when the brush is placed down upon a flat surface the bristles are maintained a distance above said surface. The paintbrush may be a cutting in brush in which the handle has a rebate so formed and positioned as to nestle the thenar space of the user's hand. The brush may have a paintbrush guard comprising front and rear casing members hinged one to the other and constructed to enclose the ferrule and bristle bundle of a paintbrush, clip means for maintaining the guard closed, and lip means formed upon the front and rear casing members constructed to engage the ferrule.
