The BA-5 Bench Anvil is a 75mm (approx.3") square block which features a flat top ideal for flattening curves and four different top edges which you can translate into your jewelry metal through repeated hammer blows. The 4 edges are a sharp 90-degree, a 1.75mm radius, a 3mm radius and a 5mm radius all helpful when forming sheet or wire.    Fretz Bench Anvils feature hardened 420 stainless steel tops that have a high polish to prevent scratching your jewelry metal. The hardwood bases dampen the sound of hammering while countersunk nylon feet to keep the anvil in place without using a vise. Made in Vietnam.
