i have heard that the civilian is a great fighting knife. if used with training like kali, intercepting incoming blows and slashes with the hooked tip will cause MAJOR dammage to opponents limbs. its not great for stabbing and thrusting but for hooking and blocking strikes it is great.
i personaly like my microtech socom clip point as it lets me stab and slash equaly.
check www.knifeforums.com or www.bladeforums.com for more info on the civilian.
as for weaknesses on the military the only one i have conserns is the knife has no liners and the handle is made of only G-10. i like metal liners in my knives for strength and butt-stroking attackers without worring if the knife will crack in my hand.
