Kitchen knives get dull from time to time. If you don't sharpen the tool, it will be very difficult to cut bread and other products.
Not every housewife has a whetstone at hand.
But you will probably find a mug. Oddly enough, this is the vessel that can help restore the knife's sharpness.
However, a mug will only be an alternative to a whetstone if it is made of a certain material.
Of course, a plastic or glass container is unlikely to help sharpen knives.
However, few housewives use only plastic and glass mugs. There is a high probability that there is a porcelain or ceramic vessel in the kitchen.
Such mugs can be used as a means for sharpening knives.
To do this, simply turn the vessel over. If you "go" with the tip along the bottom of a porcelain or ceramic mug, and then repeat the procedure many times, the kitchen tool will again become suitable for cutting food.
