A guard for protecting a finger from the blades of a pair of shears is disclosed, and includes a band of rigid yet formable planar material disposed in a ring-like configuration. The band has opposed wide and narrow ends with a gap therebetween adjustable to comfort around said finger. The band further includes a front edge oriented transverse to the finger's axis and generally perpendicular to the band's wide and narrow ends, and a rear edge angled between the wide and narrow ends so as to permit the wide end to protect the knuckle where the finger joins the hand, and so as to permit the narrow end to cover the fleshy pad beneath the finger.
