Lt. Dan is purposely stirring the pot here and waiting for opinions. In Afrikaans we say: "Gooi 'n klip in die bos en kyk wat spring uit!" "Throw a rock into the bush and see what jumps out." Well, concerning the best all-rounder, I reckon there's no such thing - my humble opinion, no one need fret about it. In my minute collection of khuks, when I want to chop wood and I'm feeling like taking exercise, I grab the 18" AK and cause havoc among the branches and logs. If the unwashed hordes clamour at my doorstep, my first thought goes to the Cheetlang. When I receive a letter and need to open the envelope, I reach for my trusty kagas katne. When my neighbour wants to decapitate the pet chicken for evening supper, I lend her my SN1 as she doesn't have a hatchet. When my friends ask me what a Gurkha knife should NOT look like, I show them my lion head khukuri. So there.
I tried out one of my kardas the other day to cut an apple. It didn't work well because the blade wedge is too pronounced. Seems to work best at skinning. So you see, every knife has its special function it can perform better than any other. (You don't have to agree.)
