It is always safer to use knife, chisel or razor knife if the blade is

• A. Sharp
• B. Dull
• C. Bent
• D. Rusted

Answer: (A)

Sharp blades are safer to use than dull ones because they cut with the least amount of force and stay on the intended line, giving you better control. When a blade is sharp, it penetrates the material smoothly and you can guide it precisely, reducing the chance of slipping and inflicting an injury. A dull blade requires more pressure, is more prone to skipping or grabbing, and can dig into the work or slip onto your hand. Bent or rusted blades are also unsafe because their edges are compromised and can fail unpredictably. Keep blades sharp and in good condition, replacing them when they become dull or damaged.
