Listening to “Glestain” would probably make you guess it is a brand or product from Europe like Germany. That is the Japanese stainless kitchen knife brand produced by Homma Kagaku in Niigata, Japan. They were established there in 1971, say Glestain is their original abbreviated name for the Great Stainless.
As you know, stainless things are harder to rust than the steel. They say that they use special-processed steel based on 440-A (A kind of steel materials) for the Glestain. The 440 has A to C, by the way, and A is harder to rust than B & C.

Number: 721TK
Blade Length: 210 mm

Moreover, the special-processed one can keep its sharpness long. Incidentally, sharpness is basically down to the configuration. What material they picked up is almost irrelevant, they say.

Number: 819TMM
Blade Length: 190 mm
Weight: 174 g
Now, wouldn’t you take a look at the blade? You will find some unique pattern. Those hollows work for heading off food sticking at a certain degree. Haven't you ever seen anything like slices of cucumber sticking to the blade of a kitchen knife while cooking? The hollows kind of save you from that situation.
I have to give you a warning, in the end. As mentioned above, they use their original special stainless for the Glestain. And it means that we can't sharpen it as doing usual knives. If you vist the Glestain world, I'd like you to be aware in advance.
