Abstract
We impose the axial and vector Ward identities on local fermion bilinear op erators in the Sheikholesalami-Wohlert discretization of fermions. From thi s we obtain all the coefficients needed to improve the theory at O(a), as w ell as the scale and scheme independent renormalization constants, Z(A), Z( V) and Z(S)/Z(P).
