When you heat it again Tonkan with cannuci. Since it is heating the aluminum foil, it has changed into work while holding the plate with pliers.


Continue to work while keeping the cannucis and pliers to cool with a wet towel.


Heat the board again ...


I will hit it.


It became considerably like a metal plate.


When you hit the board with your finger, you hear that the sound of "Kang Kong" and hitting the metal plate sounds, and it is being told that it is getting considerable hardness.


Next, in order to cut the metal plate into a kitchen knife type, we take off a ready-made knife.

I will cut it in the street of the thread with a thread saw.


Fix the board to vise ... ...


I used about this blade width.


That's why I started cutting.

A kitchen knife type metal plate is completed.


Clean the cut surface with a file.



If you scrape to some extent with a file, then use a grindstone. The first thing we use is a diamond grindstone with a grain size of # 150.

Shiso sharpen the cutting edge of the kitchen knife.


# 400


# 1000


# 2000 and so on, gradually increasing the grain size of the grindstone will increase the cutting edge's cutting edge.


The appearance during sharpening is no longer a kitchen knife.


At this point the kitchen knife is finished like this.



# 6000


# 8000


# 12000


# 30000


"Shapton blade's black screen Mirasaki mirror finish grinding # 30000"In Amazon's customer review column"I am using it for the final finish of a stainless steel knife"There is a fine grinding stone so as to have a comment that, apparently the sharpening of the movie will end here.

done. A knife with black hands is a kitchen knife of off the shelf, a wooden handle is a knife made from aluminum foil.


Size is nearly the same.


With a hand like this, it is a kitchen knife from anywhere.


It is quite sharp up to the tip, and the warpage is well reproduced.


Cutting edge from shiny to cutting edge is well reproduced.


Of course it can be used just like ordinary knives. I was cutting cucumber in the movie.


The end is stored in a box containing ready-made knives and the movie is over.


Apparently it seems like a sashimi knife that is sold in Daiso. I am amazed at the machine power that produces a kitchen knife from aluminum foil, but it is surprising also at Daiso selling kitchen knives that can be made only by this much effort spanning only 100 yen.


In addition, in the explanation column of the animation, it is written "I am paying close attention to safety, please do not absolutely do it", so please do not manage good kids.
