Open a tin can with a can opener
Using a can opener is the easiest and safest way to open a tin can. Just go to the supermarket or online store to buy some manual or electric can openers.
how to open a tin can with a can opener
Place the cutting wheel of the can opener on the edge of the can, making sure it firmly grasps the edge. Then rotate the handle of the can opener to move the cutting wheel around the edge of the can. Continue turning until the lid comes off completely. When the lid is separated from the can, open the can opener’s arm and pull it away from the can.

How to Open a Tin Can Without a Can Opener
If you don’t have a can opener, don’t worry! Here are a few effective ways to open a tin can using common household items
Method 1 Using a Spoon
Step 1: Place the can firmly on a surface. Hold it firmly with one hand and use a spoon with the other hand
Step 2: Take a metal spoon and rub the spoon along the edge of the tin can lid. The friction generated by the spoon rubbing back and forth will make the lid thinner and thinner. When the metal lid becomes thinner or worn, it means that the lid will have a gap, so we have to continue rubbing until the lid is rubbed through and then pry it open with a spoon. Do not use your hands to avoid injury
Method 2: Use a knife
Using a kitchen knife is faster than using a folding knife to open the can. Use the root of the kitchen knife to continuously knock and chop the edge of the iron lid. There are gaps on the edge after the knife is cut. Let them connect and pry with a spoon to open it.
If you use a folding knife, you need to place the tip of the knife vertically on the edge of the lid and gently pat the back of the hand holding the handle with your other hand. Until a small gap is pierced, move the knife to another position and pierce another hole. Repeat the same method, pierce the can until the gap is large enough to pry it open.
Note: Using knives is a dangerous method. Try not to use them as much as possible. Be sure to pay attention to your own safety when using them.
Method 3: Use a screwdriver and a hammer
Prepare a flat-head screwdriver and a hammer, place the can on a stable place, aim the screwdriver at the inside edge of the can lid with one hand and hold the screwdriver firmly, and use the other hand to gently tap the screwdriver with a hammer until a hole is successfully poked on the can. Repeat the operation to poke a large enough gap, and then pry it open with a screwdriver to open it completely
Note: The screwdriver used must be sterilized with boiling water
Method 4: Rough surface
Find a flat and rough surface The surface is stone or concrete, clean it with hot water, and then put the can upside down and rub it against the stone until the sealed lid becomes thinner or even worn out. อย่างไรก็ตาม, this method is not recommended because it will leave some metal shavings on the food, or the product inside will splash onto the stone. If it is not controlled well, all the contents will leak out.
