Which grooming tool is most likely to cause skin irritation if used aggressively?

• A. A rubber curry comb
• B. A soft-bristled brush
• C. A plastic shedding blade
• D. A metal curry comb (or coarse shedding blade)

Answer: (D)

When grooming, using tools that have sharp or hard edges with too much pressure can irritate the horse’s skin. The metal curry comb (or coarse shedding blade) has rigid teeth that can dig into the skin, causing friction burns, scrapes, or small injuries if pressed hard or pulled aggressively. That risk is higher than with gentler tools.

A rubber curry comb is soft and mainly loosens dirt and hair without scraping the skin, a soft-bristled brush is very gentle, and a plastic shedding blade can be abrasive but still generally less likely to cause irritation than metal if used firmly. So the tool with the greatest potential for skin irritation when used aggressively is the metal curry comb.
