If a chisel, swaging tool or packing iron develops a mushroom head on it you should

• A. Throw away the tool
• B. Use it as is
• C. Grind off the mushroom and continue
• D. Safely grind off the mushroom and use the tool again

Answer: (D)

A mushroomed striking end is a deformity caused by repeated hammer impacts, and it makes the tool unsafe and unreliable to hit with. The correct approach is to safely grind off the mushroom and use the tool again. This restores a true, flat striking surface so blows are centered and controlled, reducing the risk of slipping, chipping, or cracking the tool or the workpiece. While grinding, take care not to remove too much material or overheat the edge, which can affect hardness; after grinding, inspect for cracks or signs of heat damage and replace the tool if serious flaws are found.
