How does KaBar avoid Tempered Marstenite Embrittlement when tempering to 56-58 HRC?

I was hoping someone at KaBar could comment how they keep their 1095CV knives out of the 446° - 554°F tempering range that causes TME and still gets the final hardness down to around 57 HRC, when that implies a 2 hour tempering at about 550°F.

For anyone not clear on this concept, this article is as accurate as any other reference:

Does KaBar use some alternative tempering, or a lower quench hardness combined with lower temper heat, or is TME not a problem?

Thank you.
