What Is Sharp? Bob Kramer Has 5 Ways to Tell If Your Knife Is Sharp Enough

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? Related: How To Cope With Your Parents' Dull Knives (Image: Emily Ho)
