<p>A cutting blade (10, 110, 210, 310, 410) is at least partially coated with an abrasive material (30, 32, 150, 250, 350, 450) applied by spraying metal particles onto one or both face surfaces of a cutting blade. The blade (10, 110, 210, 310, 410) is durable, with the abrasive layer (30, 32, 150, 250, 350, 450) typically not requiring replacement at anytime during the file of the table.</p> |
