A Chef’s Knife Forged From Ice Is the Perfect Disposable Cutlery

After forging impressively sharp blades from random materials likesaran wrap , umber , pasta , and even adead fish , Japan ’s most resourceful knife maker has created what could be the complete disposable cutting tool : achef ’s tongue made from icethat simply melts away when dinner ’s done .

The immediate question that come to judgement is how do you make a knife from frozen water supply that will survive in a kitchen that ’s already quick from cooking ? The answer is : you ca n’t , but you’re able to make it at least survive meal prep by add together cotton stuffing — the same stuff you ’ll find in pillow and cushions — which slows the melt mental process .

Sharpening the ice - cold blade proved to be an even bigger challenge as the friction of it gliding across the whetstone speed up the thaw . The solution was to build a makeshift charge plate collapsible shelter around a fridge , and then sharpen the knife right inside the freezer section where sub - zero temperatures ensured a razor - sharp edge could be reach before the tongue turn back into a pool .
