A ratchet wrench comprising: a ring-shaped ratchet head with a cylindrical bore having a central axis (V-V); a handle coupled to the ratchet head for movement therewith; a drive member with a rotation axis (W-W) retained within the cylindrical bore for rotation about the central axis (V-V); a toothed ratchet pawl ; a cylindrical array of straight ratchet teeth arranged about one of the cylindrical bore or the drive member and parallel to the axis (V-V, W-W) thereof; and a pawl recess defined by the drive member and configured to support the pawl for either: meshed engagement with the ratchet teeth for transmission of rotation of the handle about the central axis (V-V) in a first direction (CW, CCW) to the drive member about the rotation axis (W-W); or disengagement from the ratchet teeth to decouple rotation of the handle about the central axis (V-V) in a second direction (CCW, CW) opposite to the first direction from the drive member, and characterised in that support for the pawl in the recess is shaped to accommodate divergence between the central axis (V-V) and the rotation axis (W-W) and the pawl comprises a domed surface which comprises at least one at least partially convex pawl surface arranged to accommodate tilt between the pawl and the pawl recess . a ring-shaped ratchet head with a cylindrical bore having a central axis (V-V); a handle coupled to the ratchet head for movement therewith; a drive member with a rotation axis (W-W) retained within the cylindrical bore for rotation about the central axis (V-V); a toothed ratchet pawl ; a cylindrical array of straight ratchet teeth arranged about one of the cylindrical bore or the drive member and parallel to the axis (V-V, W-W) thereof; and a pawl recess defined by the drive member and configured to support the pawl for either: meshed engagement with the ratchet teeth for transmission of rotation of the handle about the central axis (V-V) in a first direction (CW, CCW) to the drive member about the rotation axis (W-W); or disengagement from the ratchet teeth to decouple rotation of the handle about the central axis (V-V) in a second direction (CCW, CW) opposite to the first direction from the drive member, and characterised in that support for the pawl in the recess is shaped to accommodate divergence between the central axis (V-V) and the rotation axis (W-W) and the pawl comprises a domed surface which comprises at least one at least partially convex pawl surface arranged to accommodate tilt between the pawl and the pawl recess . meshed engagement with the ratchet teeth for transmission of rotation of the handle about the central axis (V-V) in a first direction (CW, CCW) to the drive member about the rotation axis (W-W); or disengagement from the ratchet teeth to decouple rotation of the handle about the central axis (V-V) in a second direction (CCW, CW) opposite to the first direction from the drive member, and characterised in that support for the pawl in the recess is shaped to accommodate divergence between the central axis (V-V) and the rotation axis (W-W) and the pawl comprises a domed surface which comprises at least one at least partially convex pawl surface arranged to accommodate tilt between the pawl and the pawl recess . <EOS>
