I agree wholeheartedly about the "thicker is not always better" statement - my CS LTC kukri is downright anorexic by Busse standards, and that thing not only chops like a champion, but it rides well on the belt, and is a great brush-slasher and slicer as well.

Thick knives have their place, but when they get so heavy that you'll never have them with you, they kind of lose their purpose.
