Which statement about ceramic blades is false?

• A. Ceramic blades last longer than steel
• B. Ceramic blades stay cooler during use
• C. Ceramic blades are easier to sharpen
• D. Ceramic blades are more brittle

Answer: (C)

Ceramic blades are valued for how long they stay sharp and how cool they remain during use, but sharpening them is not easy. They last longer than steel because ceramic is extremely hard and wear-resistant, so the edge dulls more slowly under typical grooming use. They stay cooler because ceramic materials don’t conduct heat as readily as metal, helping to prevent heat buildup that can dull or damage the edge or irritate the skin. They’re more brittle because ceramics are strong in compression yet weak to impact and bending, making them prone to cracks or chips if dropped or struck. Sharpening a ceramic blade isn’t easier; it requires specialized equipment (like diamond abrasives) and careful technique, and improper sharpening can cause damage.
