I have both the Native 5 salt and the Salt 2 in LC200. I regularly EDC both of them. I have noticed on many occasions that the edge on my Native last notably longer than on my Salt 2. I assume Golden and Seki does their own in house heat treatment on the steels they use? Has anyone else experienced this? Or maybe the heat treat on my Salt 2 is not up to standard. I do sharpen both knives at the exact same angle on the same sharpener. It's almost like the edge on my salt 2 rolls more easily.
