I have an older Buck 619 with the rubber grips, nylon sheath with the plastic sleeve. I think I got it around the mid 80's. Does anyone know what kind of steel Buck was using back then. It's still a beautiful knife and I almost prefer the rubber grips. I know they won't last as long as the new material they use but it's great when wet. Anyway, a few words of wisdom concerning what ever type of steel it is would be greatly appreciated!!
