The amount of radius makes a huge difference in how the anvils peens, yet no one that sells scythe anvils ever describes it. I've been trying for years to think of a way of classifying the amount of radius on a narrow anvil. Measuring the radius in actual mm is hard to relate to unless you're an engineer. Also, I don't have a metric radius gauge, and haven't come up with one yet. Classifying the radius as narrow, medium, or wide seemed too vague and relative, without a method of measurement. So I thought of comparing the radius to a common standard sized object. The best thing that I could think of was a U.S. dime, which has a radius of 9mm. According to engineer Gerhard Wagner of the SFX factory, a radius of 9-12mm on a narrow anvil is classified as a "blunt" anvil. 6-8mm is a "normal" anvil, and 4-5mm is a "sharp" anvil. The Picard anvil pictured above, looks like it has a radius at the narrower side of the "normal" spectrum.
The commonly available Czech-made "babbka's", are not rounded, but they are soft enough to shape a radius to your liking. Good luck doing that with the Picard, or the 60 Rockwell SFX anvil!
