If you're taking your kitchen knives to be professionally sharpened or you're packing your kitchen to move, you need a safer way to transport them than just tossing them in a bag and hoping for the best. Thankfully, you probably already have the solution: a simple manilla folder.
The video above from America's Test Kitchen walks you through this simple but clever idea. Just measure the size of the knife against the folder you want to use, and use the already-folded edge of the folder as a natural pocket to rest the blade against. Cut to fit, and staple or secure the open side so the knife doesn't fall out. Then you can put your knives into a bag safely and take them anywhere you need them.
