Kizlyar Supreme ECHO knife in Bohler K340 ISODUR

Bohler K340 ISODUR is an amazing knife steel. You can read about it here in Bohler's technical papers.
Kizylar Supreme are using the high end ISODUR product of K340 too!

First off, I am a long time owner of the ECHO made with AUS8, which came with a hollow grind.
Now in possession, of yet another version of the very popular ECHO, this one made with Bohler's K340. K340 is a much improved alloy over D2 tool steel. 

WHAT IS K340 ISODUR?

K340 ISODUR knife steel is:



1.1% Carbon
0.9% Silicon.
0.4% Mn
8.3% Cr
2.1% Mo
0.5% V
trace Nb and Al.

(see technical bulletin for the explanation of the Al's function-very interesting!)



"High Cutting Edge retention" is listed at the top of the features of K340 ISODUR.
Better wear resistance than D2!
"Outstanding toughness"

Certainly under random (compared with laboratory experiments) field tests, K340 ISODUR in the Kizlyar Supreme Echo performed like a dream. Cutting and carving season hardwoods (Eucalyptus species- extremely hard!).
Repetitive cutting onto hardwood food preparation boards had zero effect on the blade edge over a period of 2 weeks!



K340 ISODUR is produced by the high tech ESR (Electro Slag remelt technology).

Feathering on hardwood, easy as!

This late model ECHO also sports the popular flat grind (sabre flat). The overall shape has remained the same because it's a proven shape for a useful field knife. A full tang knife that you can feel this beefiness once in your hand. Extremely comfortable handle in any  position. 

Overall, I'm very jazzed about this K340 and super jazzed that Kizlyar Supreme brought out a flat ground version of the already popular Kizlyar Supreme ECHO.
