The present invention relates to a method of manufacturing a duplex stainless steel wire product starting from wire rod, the method comprising the following steps: roughening the wire rod surface; applying a carrier coating on the wire rod surface; peeling the wire rod using a shaving die comprising cemented carbide; roughening the wire rod surface; applying a carrier coating on the wire rod surface; and drawing to final wire dimension. In the peeling step, the shaving die used has a rake face land angle eta which is 10-30 DEG , a rake angle gamma which is 10-25 DEG , a clearance angle alpha which is 3-10 DEG , a rake face land width w which is 0.1-0.5 mm, and an edge radius which is 0.02-0.08 mm. The duplex stainless steel wire product manufactured according to the method exhibits excellent fatigue resistance.
