A hydrodynamic plain bearing has a bearing shell with an inner surface forming a bearing surface for a rotating shaft or the like. The bearing surface, in order to form a bearing having a multi-wedge bore, has a plurality of surface segments arranged one after the other in the circumferential direction and each forming a circle segment having a radius R by way of the inner circumference of the surface segments. The center point of the circle segment of each surface segment is shifted relative to a center point of the bearing shell by an eccentricity. The bearing shell has two halves, each extending over 180&#xb0; of the bearing surface and joined in a joint plane. At least one surface segment is offset from the center point of the bearing shell along an offset plane at an angle to the joint plane in the circumferential direction of the bearing shell.

A handheld power tool is disclosed. The handheld power tool has a drive oscillating along a working axis and a vibration damper. The vibration damper has a mass element suspended in a spring mechanism. The spring mechanism acts with a first spring stiffness and acts with a second spring stiffness. The first spring stiffness is different from the second spring stiffness.
