why should you sharpen your knives?
Cook’s Illustrated says it best: It is crucial to keep knives sharp so that they cut through food with less slippage. Dull knives are dangerous because a dull blade requires more force to do the job and so has a higher chance of slipping and missing the mark. Plus, poorly cut food will not cook properly. A sharp knife will produce food that is evenly cut and therefore will cook at an even rate.
