Koru Crescent Spiral Metal Sign

About the Crescent Spiral design

One white cut opens in the solid steel disc, starting as a hairline point near the top and thickening as it sweeps down the left side. At the bottom it rolls back on itself into a fat round bulb, and a small tongue of steel pokes into that curl to mark where the spiral closes. The cut sits high and to the left, leaving a broad field of steel on its right, and its upper arm curves like a thin new moon.
