First off, knives have to be placed in 2 groups. Folders and fixed blade. For a folder, I am fond of the Opinel, the Canoe knife. The Barlow and the Sodbuster. The Toothpick makes a very good fishing knife. But the perfect, do anything that a folding knife would be called on to do does exist, or nearly so anyway. The Trapper knife. I prefer the Case version with the yellow handle. Cleaning fish fowl, and game, a table knife, food prep, and just general chores. It is just about the perfect do anything knife. Fixed blade? Entirely a different story. The perfect do anything knife just doesn’t exist. A good 4 to 5 inch bladed knife comes close, but it just does not get there. Such a knife with a somewhat thin spine and a flat grind will do a lot of work, but falls short for wood processing. Give it a Scandi grind and increase the spine accordingly, and you get a decent wood processing blade, but it falls short with other chores and heavier wood processing. Increase the blade length to 7 inches and it becomes a good chopper and wood processing blade, but becomes almost useless for lighter tasks. About the best I have found is the Mora Kansbol. About a 4" blade that transitions from a Scandi grind to a flat grind, it makes a very good camp knife for general chores and light wood processing. A good fish and game knife, and a good slicer. I will continue to keep my custom bushcraft knife on my side, and the Trapper will be in my pocket. But the Kansbol, along with its companions - the folding saw and axe, will be lashed to my pack.
