Reducing the amount of work to 1/10 will completely change your daily cooking.
1. Cut the avocado in half
Three times sharper than normal
Scientifically proven 3x sharper
When the sharpness of the Perfect Knife was compared with that of other companies' products, it was found that the sharpness was about three times sharper, and that it was even sharper than other companies' knives in the same price range.
In addition, when each knife was used for cooking for about six months, it was found that it maintained the same sharpness as a new knife from another manufacturer.
It has been proven that the sharpness lasts for a long time.
2. 18 times more rust resistant
No special care required
18 times more rust resistant
Sharp, expensive steel knives will begin to rust within about 10 minutes of use, but it has been found that a perfect steel knife is 18 times more resistant to rust.
Therefore, despite its sharpness being equal to or better than that of expensive steel knives, it can be used with the same care as a regular household knife.
How is it possible to achieve both high sharpness and easy maintenance?
Perfect knives are made from 100% super stainless steel, making them highly functional.
Super Stainless Steel is the highest quality steel material, made from ultra-hard alloy steel called V Gold No. 10. It combines the easy care of a stainless steel knife with the sharpness of a steel knife.
This steel is often only used for the cutting edge, but by developing a unique manufacturing process for the Kantenmuki knife that is specialized for super stainless steel, it is possible to use this steel 100% for the blade. This is how we have succeeded in creating the Kantenmuki knife.
3. Research-proven
A knife that makes ingredients taste better
A change in taste that over 95% of people notice
Using the taste sensor Leo, developed by Keio University and AISSY Inc., we scientifically analyzed how the taste of food changes depending on the knife used, and discovered some surprising facts.
When a tomato was cut using two knives, a Perfect Knife and a mid-priced stainless steel knife, and the changes in taste were analyzed, it was proven that the Perfect Knife produced a significant difference in taste, with 95% of people noticing the umami and over 75% noticing the sweetness and richness.
What makes ingredients taste better?
The reason for this is the shape of the blade. While mid-priced knives have a rough edge, the blade of a Perfect Knife is sharpened to a smooth edge of approximately 0.001 mm.
While knives are usually sharpened mechanically, Kanzenmuki knives are carefully sharpened one by one by cutlery craftsmen in Seki City, Gifu Prefecture, a company with an 800-year history.
This allows for clean cutting without damaging the fibers of the ingredients, bringing about a change in the flavor of the ingredients. These top-of-the-line knives, created by Seki's cutlery artisans, will make your food even more delicious.
