Today by mail I received another model Carpenter HRC 66-68
with UHC (ultra high carbon) steel.
I do not know for sure, but I guess it's AISI M1017 or something similar.

In fact, here the steel is softer than stated.
My japan aquatic synthetic stone for 600 or 800 grit (I forgot the exact number)
is very easy to eat stone, I think, somewhere around HRC 59-61.

I took it in the secondary market for $30,
he was very blunt, made it sharp in 30 minutes,
While carrying him from the bath to the room (it's 10 steps),
he began to become covered with rust

The most interesting is the sheath, here they are made
of better quality leather, it is durable and does not absorb water.
Apparently the knives with steel UHC are more quality sheath.

The knife itself has more classical Finnish forms.
Fungus is not so pronounced.
In the hand lies very comfortable in any position.
