Hello!
I greet you on the do-it-yourself channel.
Recently I saw a video showing the way to sharpen a knife with the bottom of a porcelain
mug.
Many bloggers repeated this video without bothering to check this video.
I decided to check this video I found out that the surface of the bottom
of the mug has insufficient abrasiveness to sharpen the knife.
That is, the opportunity to sharpen the knife is, but it will be very long.
So I thought a little and improved the process.
As you can see, I tried to sharpen the knife for a long time, but without success.
The result is more like polishing.
Now another way.
The principle of operation is the same as in the previous video.
I found a small porcelain cup without a handle and attached it to the grinding tool of a
food processor.
For this, I cut two strips from the rubber chamber from the bicycle.
At first I tried to set the bands at the top of the cup, but it turned out to be unreliable.
Then I moved the stripes down and it turned out to be a good way.
To save the writing processor from vibration I attached the processor's casing to the table
using steel corners.
In order not to damage the case, I wound the ends of the corners with electrical tape
Now you see that I shifted the rubber bands down.
The more reliable position of the belts is due to the fact that the drawings are not
smooth, but rough.
The other end of the tape I secured from the bottom of the center axis.
The bottom of the cup was covered with glaze, so I took off the glaze using a diamond disc
for tile cutting.
Now the bottom of the cup is the same as that of a large mug.
I'll try to sharpen the knife.
The knife has become very sharp, and on the abrasive cup I see a black layer of metal
dust from the knife.
This once again confirms that it is almost impossible to sharpen the knife on the bottom
of the cup by hand, since then this metallic dust was not visible.
If you find the video useful for your horizon, rate this video.
Thank you for watching my videos.
Bye.
Until the next video.
