Abstract
An archery arrow nock (10) having a bowstring receiving groove (16) with a string contact point which is offset from the central axis (12) of the arrow to which the nock is to be attached permits the use of a lighter weight less stiff arrow by countering and diminishing the normal bending of the arrowshaft as it is propelled forward by acceleration of the bowstring at the moment of release. The string contact point may be offset either laterally from the plane containing the bowstring and arrow centerline or in this plane away from the arrow centerline.
