If this hack is as ridiculously cheap and easy to do as it looks, then I’m galloping off to try it.
Keep those sharp knives baaaaaaack!
1) Find a vase that is as tall as your longest knife. Pictured is the IKEA Rektangel, and because it’s from IKEA, no, that’s not a typo.
2) Find a whole bunch of skewers, ideally longer than your longest knife (bundle of skewers? group of skewers? what’s the count word for skewers?). Fill the vase with skewers, pointy ends down.
3) Stick your knives in there and shove the whole thing out of reach of curious little hands.
