ABSTRACT:
A stem cleaner for cutting away thorns, excess foliage and the like from stems having a flexible handle with two free ends to which are attached at least one cutting blade capable of being pressed against a stem. The cutting blade is shaped so as to prevent damage to the outer stem bark: the stem-contact surface is wide along the stem length direction; oblique-angle transitions are provided between that surface and surfaces sloping away from the stem-contact surface; and a sharpened cutting edge for cutting away the thorns and foliage is spaced outwardly from the stem-contact surface to prevent its contact with the stem bark.
