i just cleaned up a 50+ year old folder for my girlfrend's dad - the blade just says "japan" and it's got a pair of high carbon blades. I cleaned off the blade with sandpaper (500 grit only) and stropped the edge and i'll be damned if it doesn't split hairs dropped on it while it's edge-up on the table. It's a thin blade and a flat grind so I wouldn't expect it to hold up, but I had to strop it when I noticed how sharp it was despite sitting in a toolbox wrapped in an oily rag for the better part of 20-30 years.
