Marttinni stainless knife

If the company that makes the knives won't reveal exactly what steel they use, I doubt that anyone else will have that info.

But they do have a contact page on their site. Perhaps you can email them and ask if no one here knows.
 
I was told by a advanced collector of Finnish knives, that they used French stainless steel, but not what type of stainless. John
 
No idea but I can say a few things about the Marttiini stainless knife I own (Mini Chopper/Bear Skinner ~$14):

Blade came with a polished convex edge - one of the sharpest out-of-the-box knives I’ve experienced. Somewhat thicker behind the edge than your average kitchen knife, but I use it in the kitchen as a beater/squash splitter/herb dicer and it does these things very well.

Edge holding is good but not amazing. Sharpening is fairly easy compared to other stainless knives I own. Magnet test says tang extends through ~3/4 of the handle.

The guard on the handle was a little sharp but with a little filing/sanding it’s very comfortable now.

It came with a sheath so we also take it camping as our main kitchen knife.

I like it a lot.

I was wondering what stainless steel does Marttinni use and what is it equivalent to?

Stainless chromium steel​


Chromium steel is an easy-to-maintain and stainless-grade blade material the sharpness of the blade of which preserves for a long time.

A typical portion of chromium in the steel alloy is 14%, and the blade hardness is HRC 53-55. In some models, we also use high-carbon stainless steel, where the chromium content is 13-18% depending on the alloy. Depending on the model, these blades are tempered to hardness HRC 52-58. Chromium steel can also, for example, be coated with a Martef coating.

Sharpening of chromium steel can be done with a diamond sharpener. Read more.
That leaves the door pretty wide open, as no carbon content is given, and it says the stainless alloy used can vary by model.

Some of the knives on the Martini web site state the blade alloy.

Blade material​


stainless steel X46Cr13, HRC 53-55

X46Cr13 is roughly equivalent to 420HC. The steel callout used, "X46Cr13" is AFNOR nomenclature, which is used by the French.
