A cutting tool for cutting corrugated shipping cartons open includes a cutting blade and a holding arrangement for the cutting blade. The holding arrangement includes a confining member and a support member on which the cutting blade is held in its active position by being accommodated in a recess and having a stationary finger holding the blade and which is mounted on the confining member for movement between first and second positions displaced 90 DEG relative to each other. A cover for the cutting blade is mounted on the confining member for pivoting between its closed and open positions. The holding arrangement includes a contact surface which engages the edge region of the respective carton at the side wall thereof, and a distancing surface which engages the top wall of the carton during the cutting operation with the cover in its open position and with the support member in its first position to determine the distance of the cutting blade from the top wall. In its closed position, the cover either prevents access to the blade when the support member is in its first position, or maintains the support member in its second position in which the contact surface and an additional contact surface provided on the cover in alignment with the contact surface engage the respective carton at any region during the cutting operation.
