What we would actually buy The published temperature is a nice piece of honesty. The durability claim is relative to Tefal’s own range and should be read that way.
What you are getting
An 18 cm (7.1 in) santoku in German stainless with Tefal’s Ice Force treatment — the blade cooled to a stated −120 °C (-184 °F) after heating — and a finger guard.
Reading the claim properly
Tefal states up to twice the life of its other stainless ranges. That is a comparison with itself, which is honest and is not the same as a claim against other makers. It tells you this is the better of Tefal’s knife ranges.
The shape
A santoku has a flat edge and cuts by pushing down and forward rather than rocking. If you rock a knife through herbs by habit, this will feel wrong within a week.
What is not published
Hardness and edge angle. Both would tell you more than a process name, and neither appears.

The questions that come in
What does cryogenic treatment do?
It is a step in heat treatment that transforms retained austenite in the steel, and makers associate it with hardness and corrosion resistance. Tefal publishes the temperature; the resulting hardness is not stated.
Is a santoku better than a chef’s knife?
It is different. A flat edge chops straight down; a curved chef’s knife rocks. Buy the one that matches how your hands already work.
Our score
