K-Bar's are not any sort of benchmark for fixed blade knives. It's a $60 partial tang fighting knife made of mostly adequate steel. Nothing very special about them one way or another save for historical value.
What do you plan on doing with the knife?
Bushcraft? Blind Horse Knives, Bark River Fallkniven.
Hard use survival style knife? ESEE, Busse, Swamp Rat.
The list is endless unless you help by narrowing down the purpose of your new tool.
