Ka-Bar has taken a good knife and made it better. The thickness was increased from .150” to 1.65” for increased strength while the grind was raised to accommodate the new thickness and preserve cutting efficiency.
A blade thickness increase from .150" to 1.65"? Well, that CERTAINLY will increase blade strength! I doubt you'll be thin-slicing tomatoes with that blade though.
