Chasing Hammers have a large face for flattening and a ball-peen side for riveting and metal design (the "hammered" look). The forged head is wedge mounted on a wooden handle.
Take a good look at the head of a Chasing Hammer. If it is totally flat, then you will mar your wire if the edge of the hammer happens to hit it. If it is too convex, there is only a small striking area in the middle. This hammer is only slightly convex so there is a large striking area but the edges are smooth. Don't be fooled by other hammers. From a distance they all look the same with similar handles. Make sure to look closely at the profile of the face.
Do not use this hammer for stamping, the back of the shanks will mar your hammer. For stamping, you want just a big ol' nail pounding hammer (at least 16 ounces).
