My father went to Indonesia years ago, and visited some of the remote villages where folks still live a primitive lifestyle. One appreciative villager gave him a knife for a flashlight given to him. Villager still had another knife to use.
Point is, there are very, very few people that only own one knife.
Another example, look in any kitchen in the US. Multiple knives, multiple uses/purpose. Can a good chef knife do most anything? Yes, but who has just a chef knife in their house, and nothing else. Most folks use other knives more than the chef knife.
