The KNN are actually three men, farmers, who are also expert kamis. It isn't clear whether they work singly, or collaborate, or both. The bowl of the butter lamp may be the clue. In one pic on another thread, the bowl is blank. On one of my knives, the bowl has a small, deliberately made dot (looks like it was made with a sharp center punch), at the bottom of the bowl, to the left. On another blade, there is a "/\" mark in the center of the bowl. We're guessing this is their "time card" record. They work for extra income, and go back to their farms for planting and harvest, and their blades are certainly up to HI par. My KNN Malla is one of my top favorites.
