My favorite is my 17 3/4" WW II Chiruwa Satisal by Bura.
It is an extension of my arm like no other. I chop, limb and trim trees, bushes, vines and tall grasses. It has prepped roasts, sliced veggies and filleted fish, stirred a pot flip pancakes and processed game. I customized the handle, removed the ring and wasp waisted the shape and rounded the upper point of the pommel. I can chop all day without gloves and there are no hotspots.
In the khukstump there is an 18" CAK that is much heavier, I like it, yet it will fatigue my arm after using it all day. The 12" and 15" AK's are great to have and weigh nothing, chop well, yet I really like the 17-18" length. I have an 18" WWII (the one right under my 17 3/4" in pic),with a possum tang that is the companion to my favorite, yet the balance forward is different and only feels good in my left hand.
My second favorite is my 12" Pen knife, it's almost as if it's weightless and yet the belly is viscious on cutting meat.
My wife's favorite is her 12" AK by Bura, she has built a few hundred feet of fencing around the property from very hard driftwood, that's a lot of chopping and she's dead on

My oldest daughter uses her 18" Kobra by Bura to get up in the trees with me to take out strangler vines and poisen Ivy in season, she loves the speed and weight of this. My youngest daughter's favorite is her 15" Sirupati, she does a lot of good work with it. De-vining, cutting wild grapes, cattails and carries it on all of our woods walks

Have a good time and be safe
