Determining whether a knife is sharp requires a visual inspection and physical testing. Here are some signs to look for to assess the sharpness of a knife:
Visual Inspection: Examine the edge of the knife under good lighting. A sharp knife will have a thin, even edge with no visible nicks or chips. If the edge appears dull, uneven, or damaged, it may need sharpening.
Edge Reflection: Hold the knife perpendicular to a light source and look for a thin, reflective line along the edge. This reflection indicates a sharp edge where the light is reflecting off the fine cutting edge.
Paper Test: Hold a piece of paper vertically and try to slice through it with the knife. A sharp knife will cut through the paper cleanly and effortlessly, leaving a smooth edge. If the knife tears or struggles to cut through the paper, it may be dull and in need of sharpening.
Thumb Test: Carefully run the edge of your thumb along the blade at a 45-degree angle. A sharp knife will catch or bite into your thumb slightly, while a dull knife will slide smoothly across without much resistance. Be cautious when performing this test to avoid injury.
Food Test: Use the knife to cut through a variety of foods, such as fruits, vegetables, or meats. A sharp knife will slice through food with minimal effort and produce clean, precise cuts. If the knife crushes or mangles the food instead of cutting cleanly, it may need sharpening.
If your knife fails any of these tests or exhibits signs of dullness, it's time to sharpen it using appropriate sharpening tools such as whetstones, sharpening rods, or electric sharpeners. Regular maintenance and sharpening of your knives will ensure they remain sharp and effective for all your cutting tasks.
A sharp knife will cut/slash/chop easier.
A sharp knife cuts much better than a blunt knife. A sharp knife is less likely skid off and cause an accidental wound.
it is as sharp as a steak knife
A blunt knife tends to squash the fruit before cutting. A sharp knife will slice through the fruit without squashing. Less pressure is needed to slice with a sharp knife.
Sharp as a knife means smart. Just like not the sharpest knife in the drawer would be somebody who's not very smart

no because they are sharp like a knife
A dull knife rips the skin, while a sharp knife (think scalpel) slices smoothly. A dull knife would be by far more painful.
"The sharp knife goes where you send it, the dull knife goes where it wants" is a reminder to keep your edges sharp. The dull blade is deflected by a hard material.
the opposite of dull is sharp. like "the dull knife and the sharp knife."=dull means boring and not fun.=
Be careful, that knife is sharp. Don't step on that sharp rock!
