1. Observe that there is a little extra iron on the iron can, like the cigarette is not opened, you align the iron that leaked out of this point to the iron key hole, and then turn the key to open it. Just want to open the packaging film of the cigarette, but it is metal, you need to use the key to screw.

2, buy a Swiss army knife, there are special tools to open this can, imitate that can also be, but not sharp, generally should have a tool like a key can, there is a protruding strip on the can, It is easy to open the can with that tool.

3. When there is no tool, you can directly grind the bottom surface of the can on the ground, and after the flange of the flange is worn away, it is easy to open. Very simple, take the kitchen knife, tilt up, use the knife at the bottom, and make a small mouth along the circle little by little, a little patience. It would be even better if you had a special tool for canning.

4. On the side of the can, the protruding part is picked up first, and then rolled up with a special tool on the box. Find a piece of iron on the can that is easy to lift, and pass the iron through the small hole in the can opener key and roll it along the line.

5, put it on the ground and push it forward and backward. After a few times, it will wear through. If you grind a circle, you can wear off the edge of the layer or grind it, then find a hard object and put a can on the lid. The whole part was opened, and then again, the whole canned meat came out and did not break the shape at all.

6. Going to the ground and squatting, you will open it a few times, then find a hard object and gently smash the lid of the can, and then the whole canned meat will come out. Of course, the shape will be a little damaged.
