Sharp knives make cutting and prepping ingredients faster, easier and safer, we know this. But what does a truly sharp knife look like? In this short but very illuminating video, Master Bladesmith Bob Kramer demonstrates five simple tests to tell if your knife is sharp enough. (Spoiler alert: it probably isn't.)
According to Kramer, a properly sharpened knife should be able to:
• Cut the tops off of carrots while they are being held, without the use of a cutting surface
• Cut through paper
• Slice through a rolled up magazine page
• Easily slice a tomato
• Bite into the papery skin of an onion, without sliding
Kramer also demonstrates how a dull knife performs when attempting these tasks. After watching, I'm afraid most of my knives are due for a sharpening. How are you feeling about your own knives?
