Look, examine, and think about what you are going to do with the knife! The difference between a "combat knife" and a more mundane, but high end back-woods (bushcraft) do-it-all utility blade, is that the former must *sometimes* be pressed into action to either fight (rarely), or kill by suprise (something different from fighting) as in sentry elimination.
Ron Hood is fantastic, but he does have some sort of relationship to Jerry Busse. While Busse "combat knives" are great knives, they don't impress me as having been designed with any of the "killing" requirements that might be called upon from the likes of a "combat knife". First, the blade is slightly offset in angle (about 5deg) from the handle, a great feature for chopping, but not so hot for fighting. Second they are real thick, third, heavy, etc.
Have a look (just for example) at the Livesay HKR (http://members.tripod.com/~Newt_Livesay/index2.html). Now I'm not recommending this as the best over-all "combat knife" in the world, but it does illustrate what I'm saying above... The knife is long, makes it a decent chopper, digger, bushcraft utility blade. At the same time, it is a tad thinner than the Busse's (lighter for rapid handling), point is in line with the handle (fighting/self-defense), and the point is drawn out and needle sharp (sentry elimination). Thus you see in this knife, the elements of design that make it a true "combat knife" as distinct from the two alternate catagories of "fighting knife" and heavy "utility knife"...
