Shave a Friend

Knife nerds love performing the so-called “hair test”—running a blade along their arms to test sharpness. If hairs pop off without effort, you’ve got yourself a suitably sharp tool. If they curl stubbornly around the blade, it’s time to break out the waterstones. And lucky for you, we've got a comprehensive Knife Sharpening class with everything you need to know (and just updated with tons of new stuff!), at http://chfstps.co/1AMTXVi

DISCLAIMER: Really, guys, we're just being silly. You don't need to shave yourself—or your friends—to know if your knife is sharp, so don't try this at home. Learn to sharpen your knives at http://chfstps.co/1AMTXVi, then test your blade's sharpness on a tomato like a regular person.
