Abstract

The invention relates to a taping knife handle (100) comprising a gripping part (110) connected to a blade attachment part (130) by a central part (120). The gripping part (110) has a convex upper face (111) for receiving the palm and fingers of the user's hand. According to the invention, the convex curved upper face (111) is connected to the central part (120) by means of: • an engagement region (112) having a front convex curved engagement face (114) directly connected to a concave curved engagement face (121) located at the front of the central part (120), and • a lever region (113) comprising a convex lower lever face (115) located under the convex upper face (111) and connected, by a bent region (117), to a concave bearing face (122) located at the rear of the central part (120).
