A handtool device for detecting puncture openings in an interior bore surface of a tubular carrier member upon which carpet is rolled for transportation includes an elongated handle member for moving the device through the tubular bore and an adapter body member carried adjacent one end of the handle member. A plurality of resilient prong members are affixed to the adapter body member inclined to the axis of the handle member extending outwardly therefrom having free ends biased against the interior bore surface when inserted therein for engaging within a puncture opening during movement through the bore.
