Your kitchen knives are not sharp anymore, but you don't want to get out a whetstone to sharpen them.... A handy sharpener is useful in such cases. Our editorial department purchased it at the 100-yen store Seria (108 yen including tax).

Seria "Handy Sharpener

The "Handy Sharpener" is a sharpener with diamond particles that allows you to easily sharpen kitchen knives by simply tracing the edge of the blade. It has a shape that fits in your hand and is easy to hold.

Knife sharpener that fits in your hand I tried it out.

I try it on my kitchen knives at home, which have not been sharpened for a while and have lost their sharpness.


Sharpen the sharpener without water (wash and dry it well before using it for the first time). After making sure the knife is also free of wetness and dirt, hold it firmly by the handle and point the cutting edge outward. Place the sharpener on the blade and sharpen it several times, sharpening from the inside to the outside while maintaining an angle of about 15 degrees.



The key is to sharpen lightly with only the weight of your fingertips, without applying unnecessary force. Also, slide the sharpener in a certain direction.

When you are done sharpening, give the knife a quick wash and you are done! Try cutting a tomato...



It was a surprise! It went like a flash! I used to have to push and pull the knife back and forth to get a good cut, but now I can just lower the knife straight down and get a nice clean cut.


After that, I tried cutting various foods such as vegetables and meat, and it was obvious that the sharpness had become sharper. I didn't realize how easy it was to sharpen a kitchen knife. However, if your knife is double-edged, you have to sharpen both sides in the same way. Also, unlike a whetstone, you have to hold it by hand to sharpen it, so it is a bit shaky. This is a simple and easy way to sharpen knives, but you need to be careful.

It is convenient to sharpen knives with a whetstone, but it is also convenient to sharpen knives quickly and easily.
