Use of Sandpaper

Sharpening knives is not only inexpensive but can also be done at home. This is also very easy to do.
First, get a 180-grit or 240-grit sandpaper ( wet or dry silicon carbide black sandpaper). Lay the sandpaper on a hard surface to handle it firmly and to sharpen the entire edge. Hold the knife firmly to sharpen it and slide the edge across the sandpaper. Sharpen the knife from both sides in the same way. Raise the handle slightly when sliding the edge of curved blade knives.
Method # 02

Use of Smooth Stone

A smooth and flat stone is good for sharpening the knife. Choose a smooth rock that has a fine grain. Wet the rock with water and use it like a whetstone. You can move the stone over the blade if the rock is small. While sharpening, you need to keep the angle consistent.
Method # 03

Use of Concrete

Method # 04

Use of a Coffee Mug

A coffee mug is mostly available in homes, and you can use it as a homemade sharpening stone. Most of the mug’s surface is polished, but the bottom of the cup is usually rough. This rough surface is not true for every mug, but most mugs have a rough surface. This rough surface can be used to sharpen the knife. Knife sharpening will be better if the surface is rougher. Place your knife at a 10-degree angle to the bottom surface of the mug. Sharpen the knife from both sides by keeping the same angle.
