“Button Hone”, “Dingle Ball Hone”, “Ball Hone”, all the same tool. Several hundred abrasive balls about 1/4 to 3/8 inch in diameter suspended on spring steel wires. Available at every Auto Parts Store. Much more efficient than a 3 stone Glaze Breaker. Be sure to keep whatever tool you use well lubricated as you move up and down in the cylinder.
